Yamaha BBT500H, any users?

[eots]

I recently got one but have only practiced with it. I'd compare it to the new Ag500, EA iamp500, or ampeg's new digital amp. Can't remember the model number. It's got 5 presets that can be switched via midi pedal and 6 more models set manually. At $600 I figured to be a pretty good buy compared to the aforementioned. I'm still coming up with cab $$ but I'm thinking either the matching Yamaha bass cabs or a pair of EA wizzy 112's to get the most out of this amp. Yamaha doesn't give specs for the cab's other than the 1-10,2-10, and 4-10 cab's each are 4 ohms. No frequency rating, sensativity, ???

I recently put a thread up about the same head and found there had been a previous thread up about it here.

Can you tell me what the spec is on the amp as it doesn't say whether the power is RMS or not?

Thanks

Please keep informed on how the amp works out. I would really like to know good the power is and how it does in a gig situation.

About all I can say for now is, I loaned it to a buddy that has a recording studio in his basement. All he had been doing for bass was direct into the board. PPPTTTHHHH. I loaned my Carvin lb70p also, which was a vast improvement over his recent bands passive peavey p-bass. This amps line out made a world of difference. I'm not done much recording myself but I would assume there are plenty of products that would improve upon that scenario. I have heard ,though, of amp line outs that are crap as far as recording goes. This is not one of those. The fuzz and distortion settings(they are separate) sound pretty similar to each other without any eq changes and the 'heavy' setting can be made to sound similar as well. I have a Carvin pb200 combo that has 1 knob for compression so I'm used to that. The compressor function on this is a bit overwhelming to me. For now I'll just stick to a few of the presets like the 'flat', 'modern' and 'r&b'. The 500watt rating is at 2 ohms and 250@4. I'm looking to max that with 2 4ohm cabs. I just ebay'd my GK800rb and ART nightbass cause they were getting up in years and new gear has a way of getting the ol' juices flowing again.

I saw that thread after I posted mine but didn't see that anyone actually owned one. I may be one of the 1st. I have looked into EA iamp's and they are a bit pricey for me. I don't figure on ever needing that much power(i800)not that you can have too much, but it was twice the price as is the AG500. I expect the new ampeg digital is too.Plus I get a few effects w/o having too set up anything requiring wall warts or extra cords.

Looks like a couple whizzy cabs would be my choice. That 500 watt rating is at 2 ohms.

I don´t know about the sensitivety and freq, but all the tree cabs are rated at 250Watts into 4 ohms. So they are all ´made specially for the head. I said in a previous thread that the 2x10 is lacking a little in the bottom in my apinion but try it with a diferent cab or with the Yamaha 4 x 10. A friend tried it with the 2 x 10 at a medium club gig and said he really liked the sound but it was lacking in power. SO more cabs or better cabs either way I think the head is a good investment.

(BUMP)

Have any more people tried this head yet?

It's just become available here in the UK and is reasonably priced. I'm am not particularly interested in 'amp modelling', but I'd be interested if it can run a 'clean' sound.

Wow, this is a really old thread I am reviving. I have a problem with my BBT500h, it is not possible for me to dial the sound type 'fuzz' anymore. I can turn the dial to 'fuzz', but the light does not change from 'dist' to 'fuzz' and the sound also does not change. I've read somewhere that it is possible to exchange the pot but I thought it might be easier to ask if someone on talkbass could dump a midi preset in which fuzz is enabled. I don't know if anyone ever bothered to export the presets to a Computer... but maybe I am lucky and someone can help me with this problem

If the LED changes, the pot is working as designed.

The light does not change. Sorry for the mistake, thanks for the reply. I've corrected my wrong post.

Then it’s possible there is a missing control voltage signal. This can be caused by a variety of faults. It can also be that the CV is present but not being read or multiplexed back to the control processor.

Yamaha has a very good service network, I would recommend taking advantage of it.

 

[MattZilla]

Wow. I’ve never seen “multiplex” used as a verb. Probably gonna have to read that wiki page ten or twelve times to grasp it.

 

[agedhorse]

One way that all the control positions are read on this type of amp (if I am remembering it correctly) is that the output voltage of each control is read as the multiplexer strobes across each control output, generating a snapshot of knob positions based on output voltage.

 

[lazybone]

Thanks for your replies! Trying out the Yamaha service is a good idea, but I would like to try to import a preset with the 'fuzz' enabled first. Is someone here who has this amp and would be willing to dump a preset with 'fuzz' enabled to a computer?

It healed itself after some time in my cellar
Our rehearsal room is not insulated and therefore not heated properly during winter. So my guess is that it must have been some kind of humidity problem.
