Could be a really cool rig. I had a 3203 for a long time. I don’t know much about the Friedman IR line but if you could connect it to the 3203 fx loop bypassing the 3203 solid state preamp, you’d have a full tube setup! I bet it would sound killer.
It’s been a while and I no longer have the amp but I used the Tonefreak Naked OD which paired perfectly with it. I bet the MXR fat sugar would also pair well.
I have 3 of them lol, the original, dinosaur and orca. Call me crazy but I hear a subtle difference between them. I gravitate to the dinosaur version.
…and go ahead and flame me but the purple Hammett wah is also killer sounding!
