Oc2 Volume Drop

Recommended Posts

Hi folks....

I use a Boss OC2. It's a major part o my sound and I won't be chanimg it for an alternative that's for sure. I run it with the Oct-1 at full and both dry signal and Oct-2 off.

Sounds amazing... But. There is a noticeable volume dip between that and my dry signal/all other pedals. When it's run with something else, the other pedal picks up the volume, but when I use just octave it's just too quiet. If I dial the dry signal back in, that goes noticeably higher than the Oct-1.

Before I get a booster and a bypass loop to use this pedal long term (and I REALLY don want to do this as my boar is FULL), does anyone have any words of wisdom about getting around it/anyone else experience the same issue?

Shep, it's actually a fairly well-known issue. Infact, SFX used to offer a +3db mod to the OC2 -1Oct channel.

I too have the same problem - I rectify it with a chorus or LPF but I'd rather not. Infact, I'd considered getting someone to build me a small loop with a boost - something tiny but switchable.

Time for an Aguilar Octamizer I think. That thing goes LOUD. I have the Octave Level knob on about 8 oclock with the clean signal at 12 oclock and its still sooo loud. It's capable of boosting, so even without the clean signal it's easy to get the levels right!

Cheers for the replies guys.

It's just the -1oct that drips volume and all over tue fretboard. I I roll the dry back in it's same volume if not louder... But Oct-1 seems to drop a few db. Cab handles the lows fine as I also have a MarkBass super synth and the -1oct and -2oct sound thunderous and low loss of tone or volume. The OC2 however has a special tone that I have not hear from another pedal. Deliberately synthy.

Had both the mxr deluxe and the Aguilar as well as the EBS, they all spun natural and fat... Which the Mark Bass does fine... Only the OC2 sounds like an OC2 in my experience...

The SFX mod sounds perfect and I'll give Max a shout...

That's a very interesting read.

How do you power your OC-2 as well? If you run it with batteries or with a 12V input, it will run internally fine at 9V but if you run it with a 9V input it'll run lower than 9V as (strangely) there is a resistor that brings the voltage down by a few volts as the original Boss adaptor (ACA?) was actually 12V, so the pedal then needed to be stepped down to 9V...very strange.

When I didn't realise this, I got some distortion with my OC-2 and a few other minor problems but it was completely fixed once I started putting 12V into it.

Its powered off my diago powerstation at 9v. It's with max now, but when its back i may try the 12v anyway to see how it effects it. I've certainly not heard anything I don't like about the tone etc… although it does remove a few natural sub frequencies compared to playing an Octave lower. If I play 12th fret on the low B for example with the OC2 on, the tone is perfect and synthy, but I get less Sub rumble than I do playing an open Low B. At times I wan't that sub…

I have not experienced any volume drops with mine. I run it with a battery at practice and a Frontline multi supply adapter at a gig so I can run my other effects. I use both my Stingray and Aria fretless. I have oct 2 off and oct 1 and the mix around 1 o'clock.

I have been getting some positive responses at gigs latey due to the ocatver giving it some!

Perfect. The small boost has worked perfectly. Very happy :)[/quote]
he sorted a problem for me recently, and went well beyond the call of duty, by contacting the overseas manufacturer..

sfx will go far.

Interesting thread, have not noticed a drop in mine if anything a boost when in. Set mine Oct2 off, direct level at 3 oclock and Oct 1 between 11and 1. I saw this setting suggested in a bass Mag and find it about right for most of my numbers.

Thanks for the heads up

I wonder whether simply removing those resistors and then bridging the connection with some wire would help achieve the volume increase whilst retaining the pot function. Obviously the pot iteself is a resistor of sorts, but if they’re ‘off’, might have the same effect, difficult to know.

Or just get yourself a COG T-16 instead of modding your vintage pedals :). A Wazacraft OC-2 could also solve the problem Boss (if you’re reading).....just sayin’ ;)
