Volume being controlled by effect loop knobs

I have a VHT special 12/20RT amp. The volume seems to be controlled by how high I turn up the effect loop send and receive knobs. Is this normal?? Also the amp is starting to sound distorted. I tried changing all the tubes but that didn’t seem to make a big difference

Hi Bobelou,

Welcome to the community :tada:

Yes, FX can attenuator or boost the signal, when a boosted signal hits the FX return it is amplified all the way to the power tubes and the speaker. So of you inject large signal the amplifier will distort earlier.

In the FX return there will be a buffer circuit, it is unlikely that this distorting because you would really need to have a lot of signal hitting it.

Please give some more details about you setup and let’s see if we can get to the bottom of the distortion you are mentioning.

Regards,

Dan

The VHT special 12/20RT is not a Fryette amp.
