Positive Grid Bias Bass Mini 300 watt head

Post by FunkyJase » 03 Oct 2018, 10:29

Has anyone had a fling with these yet?

I find it pretty tempting but I wonder if 150 watts at 8 ohm is enough.

All my bass amps have been in that power range. I don't think you'll have issues if you have enough cabs. Loud gigs get 2 cabs, quiet gigs get 1. ;)

Would I be right in saying 150w solid state is delivered quite differently than 150w class D? I know the old GK800rb is only 300w but kicks some class D heads rated at twice that.

Depends on so many things:
What you are planning to use for?
What cab(s) you will run with - efficiency rating measured 1w@1m. A 103 dB cab will be louder than 98db cab.
Tone: mid focussed v low end heavy(more power), clean v dirty
Kind of gigs you do & pa support.

I’ve found generally 400w+ has been about low end of what works for me.
General rule of thumb +3db spl ~ double the power or double cone area

In the right application it could be exactly what you need :)

I jammed with a guitarist with a positive grid bias head. It was shit - sounded awful. He was adamant it was great. I'm sure it was... in his bedroom... at low volume. In a band situation, it just didn't sound good in the mix.

Needless to say, it didn't become part of his live rig.

That's interesting, because we played with a band a couple of weeks ago whose guitarist used a positive grid bias head and it sounded massive :shrug: … made our guitarist's Marshall sound crap … then again, our guitarist often makes his Marshall sound like crap without assistance from anyone else :lol:

It definitely wouldnt cut it for my loud Hendrix/SRV/Cream covers band. Thats a VERY loud show.
It would suit my funky soul band pretty well I think. Ive been able to get away with an Eden EX112 and Aguilar TH500 for many shows and a Fender Bassman 115 Pro cab for the slightly louder ones...
