These days the only consistent pedal is the EH LPB2ube (stupid name), which I talk more about
here. Executive summary: great tone, craptacular, fragile construction. If you buy one, take note of the screw between the tubes. It holds the circuit board up off the chassis, and will loosen over time. When it loosens enough, the chassis goes live. A trivial fix, but quite a surprise, let me tell you. I use it to amplify the guitar going into the laptop, so other effects are all software. This is easier to carry around than my old rig.
Favorite boxes over the years have been the EH Frequency Analyzer (any ring mod is fine by me), the Big Muff, the Graphic Fuzz, the Polychorus, the Memory Man (RIP, for mine, anyway...though I might be able to resurrect it), the Ibanez DML-10 digital modulation delay, the Digitech 2-second sampler, the Line6 delay modeler (whatever its model number)...and that pretty much covers what I've used.
I'm still looking for the
perfect preamp/boost/edge-of-distortion pedal which can handle some hauling-from-gig-to-gig abuse. The LPB2ube is close, but loses due to fragility. (I should note that my main guitar has semi-low-output old Melody Maker pickups, so I need the gain.)
