The SE Voodoo VR1 ribbon mic and cloudlifter came in a day early.... was expecting Friday for delivery. No amp to record though as that subject is off for repair. Time to break out the JP-2C and run a comparison to the Roadster and the Mark V. I will not flood the results here perhaps in another forum. Just not in the heavy metal mood though.... but I can get there once I power up the amp in no time.

I am finally going to give the 5881s a shot. I had put the stock EL34s in for this week and the opportunity to hear the amp roar fell through. So, I will be pulling those and running the 5881s instead. Will post my results after next week.

Don't forget to set the bias switch to 6L6...... :roll:

I thought they sounded great in person. More of a full 6L6 tune than the STR440's. Those actually sound better pushed but the 5881 sounded great at all volume levels.

I am always extra careful before I power up my TC50. The speaker off switch can so easily be hit I make sure everything is where it should be on the back panel before I hit the first power switch.

I read somewhere that Mesa's 5881s are actually Sovteks. I have Mesa's in mine at the moment. Will get to hear them over the next few days.

I would also think the 6V6 are too. EL34 are EHX tubes. All made by the same company in Saratov, Russia; Reflector corp. aka: Sovtek Mullard, Svetlana [not the =c= tube company] Tung Sol, and what ever brand or trade name that has been purchased by New Sensor and now brokered by them)

The Mesa 6L6 STR 440 is a Chinese tube (Sino or Shuguang, actually they are the same manufacturer or not, hard to tell ) generally resourced though Ruby tubes.

I'm not sure if it was the 5881s or the Nova System I had in the loop, but I had to really crank my TC50 at my gig over the weekend - like 2/3 to 3/4 full volume on both the channel master and the global master. I put the stock EL34s back in for now, but will need to further test with the Nova System and see if I need to tweak it for it's input and output signal. I've used the effects unit with another amp and had no volume issues whatsoever. Tone-wise, meh. I still prefer the 6V6s or stock EL34s. But, that's just my ears - and all through an EVM12L. While there was some similarity between the 6V6s and the 5881s, I still find the 6V6 tone to be more lively, especially on CH1.
