Hi, I am new to this Forum, although have been playing Bass for more than 20 years now. I am presently lookingto buy my next and last Rig ( hopefully ) for the next 15-20 years. I am tempted to go towards an all Tube Amp and wants to receive your input on the Ampeg SVT Classic head which pushes 300 watts of power. I am about an aggressive Tone with some overdrive underlying a la Chris Squire ( I already play Rickenbacker Bass ). I want to know the pros and cons of the Ampeg SVT Classic from your experiences for Tone, reliability and performance.
