    I've been taking names for a potential new hybrid bass head, and this rarity from Hughes & Kettner certainly has me infatuated.. You'll find maybe a whopping 5 whole listings maximum for these amps on the web as they're long discontinued and weren't common in the first place.

    Anyway, Music Go Round happens to have the cheapest listing of all. Amp sure looks fine by the pictures, but then every time I pull the listing up, it description gets to me..

    Here's the listing itself: https://www.musicgoround.com/produc...ghes-kettner-quantum-qt600-bass-amp-500-watts

    The description: "The active input jack was bypassed through the passive jack and it now has a larger range to provide optimal sound for both active and passive basses."

    ???

    ...I guess I just don't really understand how that's supposed to work... Why someone would even want to have such a rare amp modded like this in the first place. Second, I'll admit my knowledge behind the science of how amps work is quite basic. However, I know enough for this description to make me scratch my head. Like, how does it's "range of sound" get "larger" all by wiring it to only work through the passive input jack? Idk, maybe I'm missing something here. But have you ever heard of any such mod?

    I thought about contacting this store, but my gut feeling is they probably can only guess how it works slightly better than me (as opposed to a forum full people who really know what's up). Look, I know H&K isn't big in the bass world at all. This particular amp has very few demos, reviews, etc. out there. I also know you might not want to comment as you might know nothing about the amp itself. But regardless, any shot in the dark or stab at this would be greatly appreciated.

    I would be wary, especially because of the rarity. I would also restore it back to how the original designers intended. Modified gear in my book is (almost) always worth less, sometimes a LOT less.

    You bypass something around not through. Their description is not clear. Who knows what other mod surprises are in this amp. I’d bypass their offer.

    The lowest price is not always the best bargain.

    $725 (plus $60 shipping), and listed in "fair" condition. What about this deal doesn't scream "walk away" to you?

    If there is no rational and competent description of what's been done to the amp, then it would be a huge leap in the dark to assume it has been done rationally and competently.

    Run.

    Wasn't even my first choice of the litter TBH. Again, it was really the curiosity, and every time that description *did in fact send me walking away to check out the others.

    The only advantage with this one in particular that I could see was not having to deal with customs (the rest of them are being sold from other countries IIRC).

    Edit: Thanks for the input everybody! The hybrid head search continues.
