Does anyone know anything about these old Guild Thunderbird amps? I found this one at a pawn shop and it sounds amazing but it gigantic and so heavy. I don't need it at all but I sounds awesome and the reverb and tremolo work and the foot switch does too. It's actually in pretty good shape too. This is a low end pawn shop and they know they have no market for it because they mainly deal in $100 guitars and it's not in the best part of town. Should I go for it? It would literally just sit at my house but it's so cool and sounds great. They have it listed at $1000 but they'd take $400 in cash or partial trades (thinking about throwing my Valve Jr their way and a pedal or two). It's so heavy that it has 3 handles!
