We always recommend JJ valves for this amplifier. This is because they guarantee you get awesome tone and long life and they don’t cost a fortune.

Remember, JJ is one of only five manufacturers in the world. So don’t pay higher prices for valves from the same factory that have simply been rebranded by other companies.

About the amp

• Output power 35 watts
• Tube driven reverb using an ECC81 (also called a 12AT7)
• Made in California, USA.

Please note, there is an error in the User Manual for this amp which incorrectly shows the 12AT7 tube for the reverb goes in position V3. The error has been pointed out to Two Rock and in March 2024 they corrected the manual. If you have a copy of the old manual please amend it to show that the 12AT7 goes in the V2 position NOT the V3 position.
