    Anyone out there know how to get more bass out of a Musicman hd 130? I heard somone playing through one and it sounded great so I bought one. I got it home and sounds like I'm playing a Strat. Thanks.

    I use a 130 and a 150. The key for bass is to make sure you have GOOD tubes in it, and make sure it's biased correctly. I also keep the "deep" switch on all the time, and keep the "bass" control around 5. Sounds great with a P-Bass or my 12'vers!!!

    I had one of those for a while, and it had a huge low end IMHO. That deep switch made things really rumble. Maybe it's not driving your cabs the way they should be driven. :confused:

    Did you hear the "tall box" 130? If so, that one is gone!!!! Didn't float my boat. I've got a "short box" 130 now, and my 150. They both kick butt. I've got them tubed with Winged C power tubes, but I've had J.J.'s in the 150 as well, and both work well. I'd stay away from E.H. and Sovtek(Svetlana) as I've had far too many failures with them. I don't even stock thoses brands anymore.
    What 112's do you have? Was somebody asking about them in the shop?

    I had the HD150 for years and years, and it had HUGE bottom! I kept the Deep switch on, and the bass on "0" with lots and treble and lots of mids. I played through 2x15's, 1x15, and 2x12's (at different times) and it always had plenty of lows.

    I regret selling it and would like to have it back.

    If home really means home it could be a room derived problem. Try it in a bigger space, especially one with a higher ceiling, before making any judgements.

    Not sure which 130I heard. I didn't know there was more than one kind. Can I retube myself? Is there a good place to take it in Boston? I don't want to give up on it if it might sound good. I have the 112 w/ the tweed and the one with out. I bought it from RC...I've actually tried it out in a few rooms and it sounded the same. I plugged in my bm 400 right after and it had way more bass. I'm thinking its the tubes

    I also had the bass on 10 and the deep switch on and to get any bass sound I had to turn the mids a treb to 0.

    Yup.....sounds like the tubes are toast. Give me a call Saturday if you get a chance, 617-623-7100. I'll give you my tech's info. I just got my 150 back from him and it's SCARY loud and sounds amazing.

  12. You could have a cold or open connection in your preamp that's dumping all your lows. Before you go to the expense of retubing, have the head checked out. A bad pot ground will do exactly what you describe and NO amount of retubing will correct it.

    I got it working. It had been just retubed so maybe it took a little time to warm up or somthing. It sounds great at low vol but as soon as I turn it up a bit it distorts. Unfortunatly I thinks this amp is just not what I was looking for.

    Unfortunately I felt the same way about mine... I really don't miss it all that much, to be honest.

    Has it ever been re-capped? If not, that could easily account for your symptoms. Incorrect biasing could be a possibility as well.

    If you heard one and it sounded great, why not have someone knowledgable make yours sound like the other one? :eyebrow:

    I have one. It gets mucho bass and is plenty loud (it goes into a Sunn 215s cabinet). The problem I have is that when I hit a high note, I get a fuzzy, long sustain out of the note. Kinda cool, but not for me. The distortion is always there, just more noticeable in the high notes. I've got all new power tubes in (EH 6CA7's). I've had 2 technicians check it out, and both say it's operating properly. I'm selling it to our guitar player - he likes it a lot.
