WHo makes a volume/gain boost.....

DOD OD250 is a good gain boost. Other than that, and EQ pedal like a boss would work well.

 

Another vote for the DOD 250. Inexpensive, and does the job very well. It can be used for an overdrive, or a clean volume booster. I use mine for a clean volume booster with my Nordstrand.

 

I use the Boss LS-2, because when you get bored clean boosting it's still useful for something else.
Also, you can have up to 40 dB of clean boost. Useless ? Yeah, most likely .

 

It's good but also a bit expensive for what it's worth, so buying one 2nd hand should be perfect.

 

the MXR will definitely impart upon your tone a bit of its own character. I'd listen to several first.

MXR Micro Amp
EHX LPB-1
DOD OD-250
BBE Boosta Grande
Guyatone CD-3

these are just easy to find (Guitar Center) type pedals. there are tons by more high end makers.

 

What if the OP has been waiting for juuuust the right post before making his decision..........FOR 6 YEARS!!!
