    I need to get an attenuator for my 69' BB. I took a 5 year LOA from using them. I had a Marshall PB-100 that was very marginal tone-wise. I decided to stop using it when, after a gig, it became a "real brake" when I partially ran over it. I have heard great things about the Hotplate. Any thoughts on which is the safest and gives a truer tone.

    hey pman, from what i have read, Weber attenuators are suppose to be nice, and the don't suck as much tone.

    Yep, they don't at all. I did a recording test in 2007 (against a Hotplate and a Powerbrake) and the Weber was the only one to keep the tone virtually identical up to speech volume.
    Unofrtunately, the files got lost in a hard disk crash the next year...

    In general, I think that boutique, hand-made attenuators like Weber are the best.

    That's what I have been hearing. On another note, today's EL34's have lower tolerance ranges compared to the NOS Mullards, Sieman's and Dynaco's. The vibration from this amp has killed 3 sets of PT's. It's plate voltage is at 475 and runs 60Watts clean. I was told that installing rubber O' rings on the tube sockets may help, taking off the back baffle or maybe switching to a different tube may help. Any thoughts?

    Does that device have Line-out options? I didn't see any on the website. Am I blind?

    Hi,

    I have a powerbrake that I've been using for close on a year now on both a 4211 and a 2203kk. Can I ask what difference in tone you've heard? Reason I ask is that I cant hear any difference I couldnt attribute to speakers not being pushed as hard. I must admit from the one time I tried a weber mass, it was great. The added treble seemed to make up for a lot, but nothing I couldnt get close to with eq adjustment. Not bang on, but close.
    Also what do you tend to run your master volume controls at? Do you get through powervalves much quicker for it?

    Thankyou.

    So, as I understand, the Weber Mass Attenuator is the one to get. Has anyone ever heard of Ho's Attenuator. They are supposed to be the the exact same, except on is labeled "ultimate attenuator". Is $225 a good deal for the Weber Mass 150W 4-16 Ohm? What is the Mini Mass?

    I'd highly reccommend the Weber mass, the hot plate and the Loadbox.

    I use a Weber Mass Lite and it takes a 50w JCM900 down to home practice levels no problem. The box contains a dummy speaker (no cone) plus rheostat so it does a great job of dumping the power into a reactive load. It has separate Lows-Mids and Mids-Highs controls to adjust the tone balance as you attenuate more and more, which is important

    My tests were about recording the same riff (reamped) with the VOX AC30 CC2X (which was still unmodded at the time) at full throttle with the same identical settings and mic placement (an SM57 on axis), just varying the attenuation level on the various attenuators.

    The Weber kept the tone virtually the same up to speech volume - but at that point the speakers are not driven enough and the mic itself is trying to capture the sound (they're designed to catch LOUD sounds of course).

    The THD started to get brittle and harsh after -10 or -12 dB, the Powerbrake instead got muddy. Also both attenuators tend to lose the "spongy" feel of a cranked amp, they get a bit compressed after that level of attenuation. The speaker motor load of the Weber retains a very good feeling (this was not heard in the clips which, as said, featured a reamped riff, but this was my impression when playing).
