    Finding it fairly difficult to come across a decent MusicMan BassAMP. Are they still being made anymore.
    Where is a good place to start looking for some? Thanks for any help.

    Why do you specifically want a Music Man amp?

    There were never particularly common, and AFAIK they have not been made for quite a while.

    Probably one of the last bass amps was the HD-500.

    Heard one years ago when i could not afford one and it really sounded good. or at least to my ears then! I'm playing a Fender Bassman T100 all tube amp with a Fender 15in cab.

    Nothing wrong with them as amps, but @Wasnex's question is on point; why do you want a Music Man in particular? While not exactly rare, they were not especially common in their day.

    I think all the Music Man amps stopped being produced in the mid-80's, so yeah, have not been made in quite some time.

    Did a bit of research.

    FYI, The schematic for the HD-500 is dated 2001. This appears to have a solid-state output section with a tube on the front end of the preamp. I don't think I have ever seen an HD-500.

    Earlier models included the HD-130 and HD-150. The schematics I found for these are dated 1980 and 1999. Ref: Musicman Schematics - Tube amp Schematics ( I demoed either an HD-130 or HD-150 with matching cabs in the early 2000s. I was under the impression it was new. I thought it was a nice sounding rig, if you like HiFi, which I do.

    These amps had solid-state preamps and tube output sections. My understanding is they ran unusually high plate voltages and have a reputation for being hard on tubes. Looks like the HD130 runs El34 at 725V and the HD150 runs 6L6GC at 700V. 725V is high for an EL34 but within limits. 700V is way over the limits of the 6L6GC.

    You mean this BH500?

    Not sure they’ve ever existed, or been seen in the wild.

    If you mean the HD-500, those are unremarkable.

    The old tube heads aren’t special either, but look super cool.

    Their “Audiophile” cabs from about 20 years ago were excellent!

    They’re not rare but they are scarce

    There’s an HD130 with matching 15” cab on Craigslist in my area

    I can't help with the information, but certainly do own an exceptionally rare B100 combo - white pinwale with the optional EV speaker:

    My HD-130 and 212-RH cab that I bought new in 77 or 78 (and still have) came with 6CA7s which years later I replaced with EL34s. Really good amp that I used and enjoyed for many years.

  12. I see them often for sale on Craigslist. They seem to start high and sell for half original price. I’ve thought about buying one because I love the basses but I have never actually heard one in person. I was kinda hoping the ones coming out from a few years ago would have hit the market harder.

  14. Pretty sure these were made by MarkBass in Italy. I played through some in the early 2000's. Honestly, I liked them.

    They were recently, but they were made by MM back in the day. Once saw Johnny Winter use two 100w MM amps in a 1000 seat club and to this day it was the loudest show I ever saw, even louder than Kiss in 76.

    The HD-500 is interesting but had to be short lived because the output transistors were Toshiba IGBT's which were discontinued in 2004. IGBT's ended up becoming optimized for non-linear (switching) applications and dropped off the audio radar.

    Thanks for the update! Helps a lot. I heard a music man a while back. And it sounds great. Never understood how having a tube on the front end of the preamp works. How different than it is from a all tube amp

    IMHO designer intent is probably the most significant factor.

    Early 1980’s MusicMan HD150…
    I’ve had this amp for many years and it still performs flawlessly. The hybrid design is different from most since it has a Solid State preamp and a tube power section. If you like loud and clean it delivers nicely. They do run at high voltage but so far the tubes seem to be holding up just fine. You can find them on Reverb every now and then.

    I had a 1-12 combo from the 70’s and it was Awesome. One of those “kicking myself” situations for getting rid of it.
