more low end fron a musicman hd 130

What bass cabinet are you using with it?

 

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.

 

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.

 

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.

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.

 

Just keepin my eye on this thread cause I've kinda always wanted one of those...

 

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?

 

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.
