Re: Hadley - Harmonic Converger

Baja; Can you give this a minute? On the Digitech RP1000, the send/return circuit that would work best for the HC is 600 ohm send and return. If I understand correctly, this active design version has a much higher input and output impedance. Is this correct? If so, can the active design circuit be m...

Can anyone pm me or email me Torchy's veroboard for this one?
Same here, please. These photo links seem to disappear pretty quickly. Thanks.

Re: Tech21 - new Sansamps

Any circuit information on any of these? I have a Classic, but it doesn't do a Vox or a Marshall as nicely as these seem to do?

Re: Paul Cochrane - Timmy [traced]

Paulc,
I would be happy to buy one if I could figure out how to do it. However, no one seems to carry them, and the few I see on ebay seem pretty highly priced. Is there a secret handshake I need to learn to place credit (and cash) where it is due?

Re: Paul Cochrane - Timmy [traced]

Before I have a go at designing a vero for the Tim, which I have never done before and which should be educational for me, has anyone already do one?

Re: Univox - Superfuzz [schematic]

Personally, except for the fact that it's AC powered instead of DC, I've always preferred the Univox Unifuzz to the Superfuzz. It's more versatile and useful.

Re: Hadley - Harmonic Converger

Right; I think that if you require stereo, you will need two HC devices, or two HC circuits in one housing. I only use the RP-500 in mono, so I'm only interested in the XLR issue for its noise rejection qualities. I just need a single HC device, but I'd like balanced XLR in and out rather than 1/4 u...

Re: Hadley - Harmonic Converger

I'm hoping to use this build with a Digitech RP-500. It has 1/4 line outs with unbalanced signal, so I can use that if I need to. However, it also has XLR balanced outs. I was hoping to use this as the input to this build, and then continue the XLR balanced out configuration on the build output. I'm...

Re: Hadley - Harmonic Converger

I think in this application XLR is carrying two versions of the same signal that are 180 degrees out of phase with respect to each other. I think I need to invert the phase of one of the signals and then combine the two at the te HC input and at its output. Can anyone confirm this?
Thanks
