I put these in the V2 and V3 positions of a VOXAC15C1. They sound good. For the V1 use either a 'V1' rated JJECC83S or a Tung Sol Reissue. Both sound good with the Tung Sol offering a bit more clarity and gain. Both sound good with the Tung Sol offering a bit more clarity and gain.

I have put it in v2,v3,v4 position of my Peavey Ultra Plus following the suggestion of TT. I don't have a lot of experience about tubes but the clean is still sparkly and I don't notify any noise.I've replaced a Sovtek 12ax7 whit this. The crunch and ultra channel aren't noisy also. I'm satisfied and my wallet also! clean is still sparkly and I don't notify any noise.I've replaced a Sovtek 12ax7 whit this. The crunch and ultra channel aren't noisy also.

WGS G12 C/S 12" / 75 W / 8 Ohm

If you are looking for a speaker with a classic American vibe, but need a smoother more soulful top end, look no further than the WGS G12C/S. This is based on our popular G12C, but with a smooth cone, felt dust cap and just the right amount of edge treatment. This speaker works great in amps where you are going for that big American clean but just need it a little softer up top. Destined to be another WGS classic!
