I've been through quite a few OD/Dist pedals but I'm no pedal expert. A lot of pedals give me woofy fuzzy unfocused bass notes which I hate. What pedal would give me tight, focused, piano-like low notes? The big box Plexitone gets me there, sort of, but it's real finicky about which amp I use because it's so scooped. I tried putting a TS in-line with it but didn't like the results. I'm not necessarily trying to emulate a Marshall. Thanks.
