Well I got my Mini-Mass (50 Watt) today and it works great with the Ghia. The treble boost is pretty extreme, even the 3dB setting is very bright at extremely low volume/high attenuation levels. Wuth the treble switch in the off position the sound of the amp is very good, even at high attenuation levels, much better than having the amp at low volume and using an overdrive pedal. There are harmonics that come from the tubes being cooked that are just missing with OD pedals. Overall it seems to be a nice product that will work well for my applications. It took a while to get it but was worth the waite. I really liked the idea of the speaker motor assembly to present the same inductive load the amp normally sees. I just wasn't sure the amp would sound the same with a constant resistive load since speakers change their impedance at different frequencies/levels . It turned out great and i am pleased with it. I still plan to try a Z-Brake when I add a more powerfull amp (Z of course).

if you were interested, I'm sure you could call Ted Weber for advice on adjusting those treble boost settings to make them milder. Probably just a cap/resistor value adjustment.

ruger9, I thought about that but to be honest, it sounds great in the 0dB position. I just mentioned it in case someone else was looking at them so they might know what to expect. It sure works great with the Ghia. In bypass there seems to be no volume drop, with the attenuator knob set full CW (minimun attenuation) there is a slight drop (I havent measured it with the SPL meter but can if anyone is curious). With the knob fully CCW ther is just a hint of sound. Sort of like a mad mosquito (with good tone though LOL).

DC here! I've posted a question about this to Ted - in the experts-forum. We'll see what he says. Cheers: Dixiechicken

DC here!
I have got an answer from Ted in the experts forum.
If you want to change the amount of treble boost on the Minimass - lets say: If you want to change the 3 dB and 6 dB boosts to instead 1.5 dB and 3 db boost.
You would change the two radial, capacitors to two with half the üF value. compared to the two that's already there.
Cheers: Dixiechicken

I spoke with Ted a few days ago and he told me the same thing. I don't know if I will even bother though. The tone is fine at anything louder than a whisper and with it that low the Ghia tone control can compensate with a small adjustment. I think I will just leave well enough alone and enjoy it.

DC here! Yes - I'm not shure I will bother with it either. So far I've only used the Weber with my Warmoth Telecaster. I'll check out with my Les Paul and see what I think. Cheers: Dixiechicken

I bought a minimass 25w a few years ago- it just had an on and off switch and you choose the impedance. I changed the bypass cap to half the value because I found the treble compensation too bright. It was interesting because Ted said most people wanted it even brighter at maximum attenuation. I doubt it makes any difference when you have very little attenuation. It just accentuated the Ghia's swirl to a ridiculous extent. Swirl is nice but psychedelia all the time?!!! It works great at gigs where you just want to take off a little bit of volume and keep the amp sounding happy. Brett

I had to do a gig last night with the Ghia and my pedals minus my Weber Minimass attenuator. It was a tiny hall and even though I was pretty loud in there, the amp couldn't be set for that edge of grind clean sound. While I love the Ghia's clean sound and the cathode bias makes it sing, I'd forgotten how much extra warmth and sustain, not to mention heightened harmonics come from an amp being pushed. The attenuator really helps in those situations. Brett

Can it handle the Ghia cranked or do I need the bigger model? Has anyone else had any experience with the Ghia and the Mini Mass 25W Weber? Hey, thanks in advance for the reply.

[You said you had the 25W Weber. I need one for my Ghia. Is it enough you think? Can it handle the Ghia cranked or do I need the bigger model?]
I went with the 50 watt just to be safe and to allow using other Z's later on.

Good advice T-Bar while Ted Weber said the 25w was fine for the Ghia, when friends ask to try it on the higher powered amps (like a Blues Deluxe) it's a no go. It would be interesting to compare the two though in terms of operation and sound at greater attenuation. I'm sure Ted could offer advice Brett
