Have a guy wanting to trade his El Whappo for my 2 SVT410he's. I never heard any Accugroove so far, but they seem to be well liked. One of the reasons I may trade is the weight issue with the SVT's - they weigh a ton and we're picking up on playing out again soon, so... I've been playing Ampeg cabs for the past 2 years so I'm pretty hooked up on them, and they sound good. I told him I would like to play his cab with my PF500 head and Precision, just to be able to compare. Any experiences and advice most welcome!!
