sebowden Posted May 24, 2016 Share Posted May 24, 2016 (edited) Hello hello hello, I bought an OCD clone a while back to use on bass, and while it sounds great, I'm just not getting the lows I would like. I know there are blend circuits available but then I'm faced with the issue of polarity.. is there a way I can get around this? Is there any other way of getting more bass out of my pedal? Changing caps or something? Pic of the pedals guts is up, but I can add more if needed. By the way, there is no way I'm buying a separate looper pedal for blending! All the best, SB xxx Edited May 24, 2016 by sebowden Quote Link to comment Share on other sites More sharing options...
ahpook Posted May 24, 2016 Share Posted May 24, 2016 (edited) Firstly - tidy job there....all very neat and pro-style ! Adding bass by increasing the coupling caps can, in my experience, take you down a very mushy route - often as not I've found the tone changes a lot when you allow more bass. YMMV of course - some add component sockets to you can try different coupling caps to see which sounds best. Polarity inversion can be performed with a single transistor stage wired as an inverting buffer (I'd try an Alembic Stratoblaster as a good simple design - I'm pretty certain it inverts...someone will be me straight if not) HtH Edit: One thing I've been tempted to try instead of a blend, is to ape the Boss LS-2 and rather than blending, having two volumes for the clean and effected. I've had variable results with blend circuits before. Edited May 24, 2016 by ahpook Quote Link to comment Share on other sites More sharing options...

On polarity - do you mean problems with polarity of clean vs distorted ? as opposed to absolute polarity ? Quote Link to comment Share on other sites More sharing options...

[/quote] To be honest, whatever is easiest! 'Clean lows' sounds interesting. I'm not sure regarding polarity, I'm just aware that when using blendable kits sometimes there can be polarity issues.

fretmeister Posted May 25, 2016 Share Posted May 25, 2016 Boss LS-2 is by far the easiest. Good buffer in the pedal and separate volume controls for each part of the signal. Quote Link to comment Share on other sites More sharing options...

Ideally something similar to the clean blend on my deluxe muff. Quote Link to comment Share on other sites More sharing options...
bartelby Posted May 25, 2016 Share Posted May 25, 2016 I reckon you could squeeze one of these in there: Quote Link to comment Share on other sites More sharing options...

Winny Pooh Posted May 26, 2016 Share Posted May 26, 2016 Fuzzdog kits do a blender circuit for £12 that I've just installed into a Hao Rust ride. Thanksfully no Phasing issues and it works fine but unless you can read a schemo quite well it might be hard to predict if it will work or not.

[/quote] Bear in mind that that circuitry will impart some colouration from the relatively simple jfet circuit. You may or may not think that a good thing ...
