Mark iii Blue vs Purple

[seriesnuns]

I just received a blue stripe. It may need a trip to the shop. The reverb is kinda weak sounding and I'm getting a little fizzing behind notes.

Until now I've been playing a purple stripe and wanted the blue to compare tones.

The blue is hotter for sure. On channel 1 on the purple I usually ran the volume at 6-7 to get the sound I wanted. It seems it breaks up much earlier on the blue and I'm running it at 4.

Does anyone whose played both is this normal?

The tubes matter.

Yea I've been swapping them out. I have a NOS RCA in v1 which should be good. I had to try two tubes in the reverb before I got one that sounded good.

I've been completing getting a tester for all the tubes I've aquired over the years. I try my best to keep them labaled but most end up mixed up in a box.

I also have a new preamp set on order from eurotube so I'll see how it sounds when I get those in

I'm hoping it solves the fizzle I'm getting after notes. It seems to get more noticeable the higher I raise the volume pot.

My issues came down to a bad PI tube I believe.

I have her retubed and she sounds great now.
