I am working on getting a resectable bass rig. I currently play on a 1x15 Ibanez combo. SoSo. I was talking with the guys in my area music shop, and this is the set-up we decided I should probably get: SVT-3 Pro head, on SVT 210 OHE, and a SVT 15E. Do you guys know this equipment? I play a 4-string but sometimes play with an octave pedal. Will I have the headroom I'm lookin' for? Is 300 W all I need for live shows? I trust bass players over salesmen. thank for the imput. Please suggest ampeg products if you think what I listed could be replaced by a better model, and give a reason for the upgrade. Thanks for any input.
