New MXR bass synth pedal released

[GisserD]

This long after launch i assume MXR are deliberately causing delays to maintain the hype on what is after all a very niche pedal. Just my 2c

You've got a very good ear, Darren, did you come to a conclusion?

About the pedals no. 

Although the only one that interests me is the FI for its superior tracking. Just ask Q

The guy just comes across as a click farmer imho.

I just wish someone else was making video clips of the FI4!

I'd agree, but the Oc-5 was the exact same, and I don't really think that was Boss attempting to hype.

More likely they’re making them in batches and not rushing ‘all hands on deck’ to this one unit over their normal production schedules. I mean they should but…

Or rather than a trickle every month - save them up in one big bash for Christmas…

Now you’re talking.

I’m not aware that MXR/Dunlop own their own production facilities, although even if they do, it’s not really likely that a company would dime their capabilities in order to fulfill backorders, they’ll ramp up production slowly so they can find a sweet-spot between supply and demand. You don’t want more stock than you need, especially on a niche product, because stopping and then starting (again) production is not a simple task.

It seemed their manufacturing just couldn’t keep up with the demand. It’s been a big hit.

Got mine yesterday. Had a play this morning and echo a lot of the above. This is perfect for those of us who might need a synth sound for two or three numbers up in a set. The presets are fab and there’s more than enough settings to tweak. It’s a lot of fun! Tracking is good enough and I hope better when I get it on the board with a compressor. Mr Martin Allison must have amazing technique or there’s some editing in the vids! All in all a very good bit of kit that really does provide the synthiness I need.

Thanks for that, including the very helpful comment regarding tracking capability = "good enough but not as per IMA's hype" if I've read you correctly? Although tbf I guess completely understandable from IMA, given this is his baby.

Just came across this thread on TB - made for interesting reading!

You have read correctly. It's definitely good enough for the Dog and Duck! To be fair I have only had a chance to have a little play and only through a couple of basses (e.g only just realised from reading the TB thread that I might need to change some global settings OOTB!).

IMA has had time to perfect technique and, I suspect equally importantly, work out which bass and which settings work best. It's certainly not a massive detractor for what is an amazing little pedal!

 

I had a quick scan through the thread and my review would be more favourable. I play in two bands, one is very much soul/funk covers where I might need the pedal for 2 or 3 songs out of 20, and for that, this is perfect. It's taken me long enough to play bass to a decent standard and I have no interest in learning keys to get those sounds. I would also argue that the presets decently cover the sorts of sounds I'm after. Its definitely a million times better than trying to build the sounds on the Helix - I guess I could have bought IMA's HX stomp patches, but they're not far off the cost of this.

 

Ultimately it's 'horses for courses' but worth trying if you get a chance.

@Dazm66 "It's taken me long enough to play bass to a decent standard and I have no interest in learning keys to get those sounds" You've summed me up in a nutshell when it comes to synth bass!

 

I'm currently leaning a little to the FI v4 VIP, which is only £20 more new than the MXR, if I do swap from my Boss SY-200, but certainly bass-mates of mine who have upgraded their C4 to the MXR are really happy with the changeover!

I'd love to try the MXR and the VIP.  The MXR has that ease of use that made me HATE the FI v1 I had; I know its come a long way since then, but part of the reason I loved the Deep Impact is that it had everything on the pedal, no PC required etc and the MXR has that too.  

 

I tend to completely not get the argument people make when they say they'd rather just play keys to get a proper synth tone.   I feel like it's mostly bedroom musicians that think this way, oddly enough I can't just whip out a synth for a middle 8 for most of the venues I play in!

Despite years of piano lessons and messing about on synths, I still don't want to play basslines on them - for some reason it just doesn't scratch the itch in the same way as playing them on bass guitar. Can never shake the feeling I'm pressing sprung switches, I don't feel the same connection. The FI VIP gives me that playing satisfaction, it's just more fun.
