Victory Amps Sheriff 44 Heritage Series 44-Watt Guitar Head 2010s - Black/Gold 2010.

Foot switch included.

Amp has been professionally modded.
It now behaves Like a plexi, volume I is normal channel, volume II is high treble. Channels are jumped. Foot switch now Works as a solo boost. (Connect foot switch to channel 1 input.)

Normal channel is less bassy and Works great with pedals. High treble is less aggressive as classic plexi (smaller bright cap). Very balanced amp and stands out in the mix no problem and it is reliable after mod 100%.
Also useable at any volume since master is PPIMV.
Has valve driven FX loop.

So basically it has a 1959 SLP topology, so Volume I is normal channel and Volume II is treble channel, but normal is not that bassy and treble is not that aggressive as on normal SLP.

Than the signal goes to FX loop, send part is buffered and return can switch how much signal goes to phase inverter, something like +4db/-10db switch (switch is on the back, repurposed the bypass switch which was useless anyway).

This also affects how much clipping happens on phase inverter giving you option on how much clean headroom you want since on plexi the first stage going to overdrive is actually phase inverter. The master volume is after phase inverter (from the factory), so you can use it at home and it does not affect tone too much.

The footswitch works as a boost, but of course if you will use it with a lot of gain it boosts less since amp is already compressing, so depends on the settings.
The channels are internally jumped so both work all the time, but of course if you put any of the volumes on zero that channel is silent and only the other one is making sound.

All the other switches for power reduction work normally, so you have 30W and 7W option, but it has very good master volume so even in home I use it on max power.
I had couple of friends test it, to see if they like it since tone is subjective and all loved it, one has standard sheriff and he confirmed it is much better like this then stock.
That is pretty much how the story goes.
