Re: Boss od-1
The OD-1 arrived today. its cool. quite loose and spongy and with a lot of attitude. It sounds better than my fulldrive. Its clearer and looser at the same time. Maybe its because it has no tone circuit. The fulldrive was either too bright or too dull by comparison, whereas even tho the OD-1 has no tone control, it just seemed to sound great and didn't need any adjustment.
The downside is that it does not provide much in the way of level boost - pretty much none at all when the drive knob is at minimum and the level is at max. I did the mods recommended by analogman which really didn't do a whole lot (c1,c6,c7) i also changed c2 which seemed to give a little more punch. I changed c3 to tailor the bass response, but ended up returning that back to stock, which is what sounded best. Plenty of snarl.
I've ended up just maxing the level and then using the overdrive to add the meat and veg. Thats fine, it still gives plenty of grunt that way.
Anyways, yep its definitely a really cool pedal. Maybe nice if i could have more boost volume wise, but its really just my eyes telling me that the level control should be around 12 o clock rather than dimed. The grit gets pretty hot pretty quickly.  I guess once the clipping diodes max out there is not much more they can do except sustain a bit longer.
Long story short: great, loose, organic, old skool sounding overdrive with bags of attitude and nuance. It even sounds great on its own thru a twin reverb.
