### ⭐⭐⭐⭐⭐ Great Tubes
*by J***H on July 1, 2026*

### ⭐⭐⭐⭐⭐ Sounds great in a DOD VGS50 Multi-FX pedal.
*by L***Z on July 20, 2026*

I have an old DOD VGS50 multi fx pedal from the 90's. I always hated the weak distortion sounds on it. I replaced the tube with one of these and it made a massive difference, surprisingly. The distortion has a lot of bite now.
