For those with onboard Phaser

This may have been addressed already, but I want to share a nifty trick you can pull off with your Music Man amp.
The rate of effect knob can be pulled out at any point and held static. Then the effect can be enabled/disabled via the footswitch.
I have discovered that when the effect is held static (knob pulled out), it works as a nice tone booster. I use a tube overdrive in front of the amp, and when I switch on the phaser, it produces a nice fuzz-like tone.
So what I'm saying is, if you've got an onboard phaser (such as my 212 HD-150), then you've got a built in tone/fuzz booster for solos, if you want it...
Groovy eh?

dude i didnt know hd's had phasor
i though Rp's only?
WTF?
send in a photo man
Cheers

Here's a pic of my 212 HD150 with phas0r.
I guess it's pretty rare because I've never seen another one like it.
The phas0r is pretty trippy.

Steve, what the f*ck, has anyone seen one of these!!!!!!?????????

When Music Man changed to the 150 series in 1980/81, they replaced the tremelo circuit with a phasor. All 75 and 150 models have the phasor to my knowledge. It is a cool and unique feature!
Steve

wow, thats cool.

Here's a better pic :

Yeah. I also have an hd150 with the phasor. You can get some real sweet tones in manual mode (braging;-).

Im not familiar with the phasor. What exactly is it and what does it sound like?

It's their product name for a phase shifter. Just about every effects company has one. MXR phase 90/100, or EHX's Small Stone (didn't they have the Big Stone yester-years, or is my memory failing me). It was a very trendy effect in the late 70's. *Everybody was using it*. In some cases, it was even over-used.Already the tremolo circuit was pretty much looked at as a 'has been' effect. Obviously MM had recognized that, and had replaced the tremolo with a phase shifter.

It's akin to a wah pedal. Set it at a specific point
and you can get the precise tweak tone you want. Very cool.

I have a phasor on my rp100. I like it a lot, but there's no way you can pull out that knob.
Is it possible to mod it, or to add an expression pedal to it somehow?

I am looking to get rid of my 210hd 130 loaded with EVM 10s if anyone wants one.

Yeah, the phasor-"moving in stereo". Try not to get dependent on it. The knob is so you can get the wave in synch with the band, I guess, though it seems to ride on the dynamics of string attack, ie., as soon as you start to really swat the strings, the phasor kicks in. Seems to drive the amp louder, and into more dirt. Yes, pull the knob out and the cycle is neutralized, but the drive remains. Still, I miss the tremolo on my missing HD 130.

I designed the original phaser section in these amps. They may have undergone a revamp around 1981/2 when I left. For some units, you could quickly bring the Rate control to zero to freeze the phaser in place. It wasn't by design - it just happened that way on some units.
