For now, we just have the B112-VT cab to pair with it. There is discussion for a matching cab but that has not been finalized, The amp will be available in the UK but I don't have an exact release date as of yet,

The concept behind our SansAmp DI's was that you would plug your bass into the DI and send the parallel output to your amp and use that as your stage monitor and send the XLR output to the PA. Pretty much the same way you would use any DI. The difference being that now you have a DI with amp emulation and tonal capabilities whereas most DI's just sound like your guitars pickups. The 1/4" output allows you to use the pedal into your amp for additional tone shaping etc. The speaker emulation is a fairly mild curve and is designed to work through a traditional bass amp speaker as well as direct. No matter how you slice it, running the same signal to radically different sources like a bass amp with it's own preamp and a flat response PA will always result in a compromise. Removing the speaker sim on the amp input would make the pedal much brighter in which case you would have to compensate by either changing the EQ on your amp or on the pedal. Changing the EQ on the pedal would then change the sound at the PA. This is why we recommend setting the EQ on your bass amp fairly flat when running the pedal in front. We have many users that run the pedal into their amp as well as the PA and have success. For most situations your sound presented to the audience will be a mix of your stage sound and the PA.

The wattage of the VT Bass 200 is about 150 watts with its internal speaker. With an 8 ohm extension speaker it's 200 watts.

The dUg DP-3X will be a 9 volt pedal. I don't think a manual has been written for it yet as the pedal is just being introduced.

It's best to stick with the manufacturers suggested rating. Running a bit higher (8 vs 4 Ohms) you will lose some output but there will be no tonal change.The only time I've ever blown a power amp was running at 2 ohms and I wasn't running it hard.

I'm comparing to other forums and I already use glasses.

I'm on a computer.

Is it just me, but I find this new site very difficult to read. I've increased size to 110% and compared with TalkBass and some other forums and the text is on the faint side. Not everyone is a millennial with 20 something eyes. This is text from another forum "Any opinions, thoughts, or first hand experiences would be welcome!"

One thing to keep in mind with the VT Bass or any of our SansAmp products. They are amp emulators and can obtain output type tube/valve distortion "independent" of volume. If you're running the VT with a lot of distortion to get the equivalent sound out of a vintage SVT and 810's you would be extremely loud and would automatically adjust your playing to the volume level. If you took the same SVT stack and put it in isolation and could only hear it through headphones or studio monitors the actual amp would seem overly compressed. To get the best results with our products we recommend starting with a cleaner sound at gig level and judiciously add Drive. If you use the same amount of Drive level that you use at home it will probably be too much and overly saturated at gig level when competing with drums and guitar amps.

What the OP is talking about does exist but more for the guitar amp market not for bass amps. Weber makes a device to change and match impedances but it is only rated for 100 watts. You could hook up a dummy load that that would be able to absorb the power of an amp but resistance based loads don't represent the reactive load of a speaker so the sound can be a bit flat. Most guitar attenuators on the market are designed for 100 watt guitar amps not 300 watt bass amps. We have load resistors for test purposes here and they handle about 400 watts. Tube or valve amps have output transformers which is why they will deliver the same amount of power into different impedance loads. SS amps by contrast don't have output transformers so their wattage will change when hooked up to 2,4 or 8 ohm loads. I wasn't quite sure what the OP was looking to accomplish.

Unfortunately I don't have the figures handy and my engineer would probably have to measure the unit. What I did find out is that the Rumble filter isn't really suitable for bass guitar as it was designed to reduce the body resonance of an acoustic guitar when using the SansAmp circuit. Probably around 100 Hz. The "Air" filter raises the cutoff frequency of the speaker sim in the SansAmp circuit to allow more high end for an acoustic instrument. If you want a true HP/LP filter you are better off with our Q\Strip.

It's best to contact customer support for problems of this nature. Sometimes the actuator spring can get misaligned. They can best tell you how to fix it. [email="[email protected]"][email protected][/email]

Cab sims are in reality "microphone" sims. They are designed to emulate the sound of a mic'd cab through various microphones. No cab sim will transform a smaller cab into a larger enclosure. You can maybe get somewhat in the ballpark with a cab sim or just using EQ but you can't recreate the physics of moving air molecules.

There is no easy answer. Usually with a passive ABY it should work. If the ABY is buffered it probably won't. I've used an old Whirlwind ABY like this and it works fine with pedals. With rack mount units not so much. It seems there is some bleed through. You might be better off with a small passive mixer.

[quote name='NancyJohnson' timestamp='1499794584' post='3333683'] People of Tech21NYC, could you verify whether the ABY box method would work? [/quote] If by ABY box you mean running it in reverse, sending the outputs of the preamp to the inputs of the ABY and using the i/o ports as the output it can work. It will depend on the ABY box though. [quote name='Jack' timestamp='1499795254' post='3333691'] Whilst I can't defend Wolverine's stupid comment, it does seem as though 100% of the bassists on here have said they would have massively preferred a switch to an internal jumper. I know I would. You're right, you designed it for Geddy and not for us, but still, we're the ones who'll be buying it. Or not. [/quote] For those that wish to reconfigure the product they can contact our support staff for instructions. [email="[email protected]"][email protected][/email] [quote name='Wolverinebass' timestamp='1499796865' post='3333704'] Well, having a bad day, so a bit more tetchy than normal. Apologies. Fair enough it's designed for Geddy. I think it sounds great. However, not everyone uses 2 cabs do they? Some people might still want that sound, but use a mono, single cab system. I just don't get why you'd leave it so you have to take it apart to change this when I assume it's not a big deal to put a button on the front or back to change the setting. Say for a gig in mono, but recording in stereo? I just prefer flexibility. Maybe that reads as more of a legitimate concern than what I posted. [/quote] I actually don't offend easily. No need to apologize. In the end it wouldn't be a GED-2112 preamp had we changed the existing format.

[quote name='Wolverinebass' timestamp='1499759866' post='3333331'] That's pathetic. Internal jumpers? A switch, Tech21 you total idiots! Put a switch on the back! Did that really save so much r&d time when that got tossed off?... [/quote] Kind of an overreaction and rude response. Anonymity seems to bring out the worst in people... The GED-2112 was designed to Geddy's specifications. It's set up for the way he uses it. There are workarounds through... The dUg can be ordered for use with different voltages. If you have a US version a qualified tech can set it up for use in a different country.

When you say you are experiencing clipping is this on the XLR to the PA or the 1/4" connection to the amp?

There is a mod on the VT Bass pedal to disable the high cut filter when the speaker sim is disengaged. The "bite" switch when engaged is the stock VT Bass sound. It adds a presence boost and subsonic filter that gives distorted sounds more focus. The speaker sim on our SansAmps utilizes a gentle EQ curve that was designed to work with a traditional speaker as well as when running direct. It does not have a brick wall treble cut like some digital speaker sims.

[quote name='Al Krow' timestamp='1494956367' post='3299977'] Love it when the guys who actually make the gear respond to BC queries. Cheers Tech21NYC! Now can you ship me a PDDI at a decent discount please, (because Lozz is keeping his spare, well er...as a spare!)? [/quote]

While there is some overlap in sounds with our products you can't duplicate what the Bass Driver DI does with the Para Driver or VT Bass and vice versa. Our SansAmp's are amp emulators and if used in front of another amp the EQ of the host amp will sometimes override the sound of the SansAmp. The Bass Driver is designed for players that want "that" specific tone and the ability to get it easily. A more modern aggressive tone. The Para Driver DI has a semi-parametric midrange control and is more open ended in terms of tonal control. It also has more gain or distortion available as the midrange is placed before the SansAmp circuit. It does not have the ability to get the sound of the Presence control that the Bass Driver has. The Para Driver can also be used as a clean EQ by turning off the Blend control. The VT Bass DI is designed to get different Ampeg era tones. It can also run full range if set that way. If you think the pedal is not cutting through there are a multitude of factors. How you're monitoring, the power you have available etc. I recommend setting the unit on the clean side when playing live and gradually dialing in the Drive. High Drive settings may work in isolation but may compress too much when playing with a hard hitting drummer and loud guitarist. Unlike vintage tube amps the SansAmps distortion and tube compression are not volume dependent.

The Q\Strip was inspired by those old vintage console EQ's but it is a unique design. The intention was that it would be a "musical" vs "surgical" type of product. While having different Q parameters might come in handy for a mastering engineer we chose a medium Q that makes the most sense for musical instrument applications. The use of Mosfets was intentional for the sonic benefits, low noise and also so the unit could be phantom powered. Bipolar transistors would be too power hungry. In the end I would suggest trying one. Specifications are meaningless if you aren't happy with the tone or ease of use.

[quote name='Jack' timestamp='1492624720' post='3281777'] Subbed, liking the idea of this. I do have a few questions for Tech 21 if you can answer them, thanks for all of your information so far! What's the output voltage? I'd be looking to pair it with a QSC that ideally wants 1.1V How much of a chew on is setting the internal jumper? [/quote] It will easily drive that amp. The deal is with any amp you don't want to be running the amp at it's maximum wattage. You will have no headroom for transients. Most modern digital amps have internal limiting to prevent overload but they aren't foolproof. Changing the jumpers is fairly easy. You just take off the top of the unit and change the position. There will be instructions when the production units ship.

[quote name='buff' timestamp='1492549809' post='3281208'] Would like to see a side by side comparison with the VT pedal, just to see what your getting for twice the price. [/quote] They are not comparable products. The VT Bass is an amp emulator. The Q\Strip is a vintage style EQ that can be used on a multitude of sources. It doesn't have the distortion and overdrive characteristics that our SansAmp products offer.

[quote name='nash' timestamp='1490721495' post='3267402'] Their take on the JHS Colour box? [/quote] Not really. I haven't had first hand experience with that box (JHS Clour Box) but it is designed to get "intentional" distortion. According to the description on their website it has an extra gain stage in series. It looks like a cool box. The Q\Strip is designed to be a vintage styled EQ. A powerful tone shaping tool. You can also use the LPF filter and EQ for speaker simulation.
