Soldano Custom Amplification Post Master Volume Effects Loop Mod

Fabulous news!!!

The Soldano Custom Amplification, Super Lead Overdrive (SLO-100) post master volume effects loop mod is now available. You can have it installed on your new amp during the build process for an additional ($500.00), or you can have it added to your existing amp for an additional ($600.00).

Mike Soldano personally hand wires this mod, and it takes almost all day long to do so. No one knows this amp better than Mike; so don’t take any chances damaging your amp, or voiding your life long transferable warranty with others trying to modify this loop. Let the master do it.

For those who are familiar with the Soldano Hot Rod 25 and its post master volume effects loop, this is where I came up with the idea of making this type loop available for all SLO-100 customers. Mike has done a few SLO-100 effects loop “one off’” builds for customers in the past, but none have been designed from scratch and built like this new production mod.

As the name implies, the effects loop is now located after the Master Volume controls with the EFFECTS RETURN going directly into the power amp. (FYI, current build +4db serial line level effects loop SLO-100’s have the loop located before the tone stack.) There is an EFFECTS LOOP RETURN LEVEL control located on the back of the chassis right next to the effects loop jacks. This control adjusts the power amp’s sensitivity to the signal level coming from the output of the effect device (s). More simply put, it is the volume control for the power amp.

The Master Volume controls on the front of the amp now act as EFFECTS LOOP SEND LEVEL controls. They will adjust the level of the signal going into the input of the effects device (s). This configuration allows both send and return levels to be adjusted to accommodate virtually any type of effect device (s).

An added bonus is that you can now use your SLO-100 as a power amp if you wish. Simply plug any signal source into the EFFECTS LOOP RETURN jack and use the EFFECTS LOOP RETURN LEVEL control as an overall master volume control.

When nothing is plugged into the effects loop, the EFFECTS LOOP RETURN LEVEL control is still active and acts as an overall master volume control. Mike recommends setting this control at around the 3 o’clock position when there is nothing plugged into the effects loop. You can then use the Master Volume controls on the front of the amp as you normally would.

You asked for it, and we asked Mike Soldano. You now have the option of having this new effects loop installed on your SLO-100, have Mike adjust the current +4db serial line level loop to be more pedal friendly, or just go with the tried and true +4db loop that Mike designed and still builds 31 years later.

If you have any questions, please let us know ASAP.

and........I have the first one to roll out of Mike's shop on a brand new 3 mod SLO. New 412 Soldano to go with it.

The amp ticks all the boxes for me now and is awesome. Very low noise floor at any gain level and send levels (old masters). The PPIMV (loop return) is nice at any level.

I like to run an outboard EQ in the loop of almost every amp to fatten things up and it is wonderful in this new one.

Classic rock to metal, it works. Big thanks to Lynn and Mike. I almost ordered #2.

Shit! I just realized that I'm still "it" from a game of tag in 1978...
