Re: Is anyone else stacking overdrives or boosts?
Back in my pre-rack days I ran a Boss SuperOD into a Distortion+ (SOD set for boost - level up, drive about 9 o'clock), into a pair of Baby Gorillas, or a home stereo receiver.
When I first got my Digitech Legend, I'd max the Input volume knob to boost the internal drives, but couldn't get cleans. Once I backed the Input volume down and cranked the Output, I got cleans, but the drives were too weak, so I found out that if you max the Compressor in it, it boosted the distortions nicely, and even without the internal Noise Gate, was surprisingly quiet.
I keep the Input volume on it about 9 o'clock, and the Output volume about 3 o'clock, and the input meters are still bouncing halfway up.
With the M13, I've been experimenting with boosting the unit's distortion pedals with the internal OD/boost pedals, but haven't yet settled on a combo I'm happy with, so I just use my 2 BK Butler Tube Drivers, one into the other. By itself, just the one doesn't really do it for me, even when acting as a boost for the Marshall. To be able to get cleans from the Marshall, I gotta back its Gain down, which means the Tube Driver has less to work with, so the TD in front of that helps.
I can use one for most rhythms, except the really heavy stuff, and kick on the other one for solos.
