I picked up a 2nd hand Fender Supersonic 22 yesterday and it's just the ticket for my needs.
But it's noisy.
My ISP Decimator noise gate in the effects loop totally cures it, but it's biting off the reverb trails.
So the reverb comes before the effects loop? Is that standard? Wouldn't it be more sensible to have it go after the loop if possible?
So I guess my options are:
1: some sort of mod to lower the noise?
2: some sort of mod to put the reverb stage after the loop?
3: use a reverb pedal in the loop after the gate.
Does anyone have any thoughts? Thanks in advance!

Modding the amp to swap them is unlikely to be simple, if feasible at all.
Is the noise from the amp from just the overdrive channel?

I think it might just be a noisy amp due to something that both channels share (but not the reverb tank) prior to the loop.
That seems to be the experience of a few different users from what I read online. Some people report improvements by replacing some of the caps.
I was sure I had one in my valve draw, turns out I didn't.
I tried a sovtek 5751 (70mu) and a GE 12AT7 (60mu) but could barely hear the reduction in hiss.
Next I tried a Bugle Boy 12AU7 (18mu) and it was great! Almost silent running. Amp is not as loud and the gain feels slightly different, but I like it. Still enough volume for my 5 piece band, I'm sure.
I'm just after reassurance that I'm not causing any harm with this valve substitution? And that I won't be going through a 12AU7 per week!?
Is it worth sourcing a 12AY7 to see if it's any good?
In some of their modern amps Fender have used such small resistors that even a 12AY7 can blow them - including the Bassman RI, which is doubly frustrating as the *original* Bassman was intended to use one.

Also, by using a lower gain valve you're not actually fixing the problem, just covering it up with a band aid.

Any opinions on the other mod in the you tube clip?
Anyone tried it?
The V4 valve swap does help, as does a noise gate in the loop, although that does come before the onboard reverb meaning gated reverb. A reverb pedal in the loop after the gate solves this, but that's extra faff/expense etc.
I tend to use my 5-watter at home and gig/rehearse with the SS22 at volumes where the noise isn't an issue. I'm using it mostly clean with all pedals in the front end nowadays, and it really doesn't bother me that much.
And what 5 watt amp do you use?
My 5 watt amp is one I made myself from an Ampmaker kit.
