Effects loop for old Marshall

[Mad Axe]

I’m thinking of adding a non-invasive effects loop to my ‘71 Marshall Super Tremolo.

I see that the Zero Loss is no longer available since Metropoulous is out of business and the original designer of it hasn’t re-started production yet.

There are a lot of similar looking alternatives out there, Granger, Evolve DIY (Headfirst), Mojotone, etc. Are any of these equal to the Metro loop as far as being transparent? I like that the Granger has accessible trim pots for send and return level but the most important thing to me is minimal tone loss.

If it matters, the amp already has a pre-phase inverter master in it that I am very happy with, I’m more of a boost the preamp than crank the power amp guy.

By far the best out there right now is Jeremy’s at ground zero. It’s an improvement on the metroloop - I know what he’s doing and it’s as good as it gets and better than a true tube loop IMO.

Is it something I have to message or email him for? I didn’t see it listed on the website..
