We built a Bluesmaster type OTS20 Lunchbox amp.  I call it the BluesBox, lol.  The BluesBox is to the OTS20 Lunchbox as the Bluesmaster is to the HRM.  The tone stack and PAB switching are wired like the Bluesmaster.  We really haven't played the crap out of this amp yet, but it sounds like you'd think.  More Fendery on the clean channel and kind of brassy on the overdrive channel.  Check it out and see what you all think.  And check out the variable slope control.  We call it the Allegiance Knob.  It leaves the rock/jazz switching intact but allows the slope resistance in the tone stack to be varied from 50k to 100k.  It's kind of like a Marshally/Fendery control.  Revisions are shown in red.
