In the last year I've been sipping the octave pedal kool-aid and have really found some interesting sounds when practicing at home. But, of course, once I go to rehearsal or live situations it all goes out the window - even at a recent jam session running into SVT head with an 8x10 bottom I could hardly hear any of the effect. This has made me wonder what rigs people out there in TB land are using with good/decent results when running sub octave tones. I keep coming back to running a preamp into a powered sub cabinet but am not sure where that might lead. Any help/insights would be greatly appreciated. Thanks.
