I just picked up one of these online. It sounds ok, just need a little more bass. Does anyone else have one of these?

Not trying to justify anything about the guts of that pedal, but I have built pedals with far better gutshots that have failed me and also had far worse builds that never had any problem and have been abused for years.

I wouldn't sell a pedal that look like that, but that's just me.

Besides that, yes it looks like a Dr. Boogie.

Yeah the innards look a lot like a '80 DIY something.

Thanks alot to the eagle eye posters on here. It is a Dr Boogie (Boogey) clone, and I found some ideas to fix the bass response. C11 and C12 need bigger caps. 1uf in C11 and .47uf in C12. Here is the layout in case anyone needs. I'll let you all know how it comes out.

I agree, its not the cleanest work inside, but I only shelled out $39 for it on eBay. It's a 2011 r3fx pedal. I'll see what the mods do to it, if not, I'm sure I can recoup the money back on ebay. :D
