I've been trying various overdrive pedals in front of my Mesa Boogie
Lonestar Classic 2X12. Here's a A/B of the Digitech Bad Monkey and a stock Ibanez TS9. My initial take is that the $39 Bad Monkey holds up well to the $99 TS9. Hard to tell much of a difference. I started out with the TS-9 with all the knobs at about 1 o'clock. I then tried to match it with the Bad Monkey and have the level at about 10 the low at about 1, the high at about 2:30, and the gain at about 12. Used my American Deluxe Strat
with G&L pups and a Heritage H150CM with Duncan '59s.
All was recorded via SM57 to mixer, to soundcard.
A friend of mine just ordered the BB Preamp so I might have the opportunity to ABC these pedals later this week. Out of the bunch, I'd like to settle on one.
