    For sale is a late 60s Guild Thunderbass head in splendid form. I have a few of these things and am only selling in order to thin out my rig a bit. Only a few months ago this amp was recapped and retubed by Arkham Amps (www.arkhamsound.com). Will be shipped quickly and competently for $65.

    Some things:

    Recently nearly fully retubed (wonderful RCA 6L6GC tubes happily have lots of life in them)
    All 16 electrolytic caps recently replaced.
    New fuse holder installed
    Power socket installed
    Some drifted resistors replaced

    For those like me unfamiliar with these amps - how many watts (into how many ohms)?

    It is a 50 watt head into 8 ohms. This last is debated among the Guild crowd, for there are two jacks in the back, one for an 8 ohm cabinet and one for an "ext speaker". Some are of the mind that it can handle a total of 4 ohms (an 8 ohm cabinet in each), others only 8. I've only ever run it at 8.

    Hello Rich. Between your two Thunderbass heads for sale now, which is better: "mighty clean kit" or "splendid form"?

    "Mighty clean kit" is just a shade better than "splendid form"; though, the head described as such doesn't have as many cool mods.

    My first bass head. Mine needed service, and I was young, ignorant and amazed someone had given me a bar band gig. Ahhh.... Memories. I'd love to pick one of these up and hear how they're supposed to sound. GLWTS!
