It's the second stage of upgrade for the little amp. I bought the 600 with intent to use it as a project amp. The first upgrades were grill cloth replacement, an upgrade to a Jenson MOD6 speaker and a tube change. At that stage, I replaced the factory tubes with a JJ 12AX7 and a JJ 6V6. The outcome was mixed. The amp now sounded like a real Fender amp. It also became much louder. What it lost was the jazzy mid-rangy tone that first caught my ear. The electrics I use are a Godin 5th Avenue Kingpin and a Fender, Thinline Telecaster. That's were the EH 12AY7 comes in. It's restored a bit of the amp's mid-range fullness, but without the mud. It's also noticeably reduced the volume output which, for my purposes is great. The sound now begins to break up at a volume suitable for coffee shop/wine bar gigs. It's also tamed some of the amp's hum (it's most annoying trait). Bottom line: If you're trying to coax a bit jazzier sound from a Fender amp and don't mind (or like me, actually want) a bit of volume drop, The EH12AY7 is worth a try. Review: I put one of these in my Blackstar along with an equalizer in the FX loop to help reduce the gain and if worked great. ## Features - Brand: Electro-harmonix - Power source type: Electro - Brand: Electro-Harmonix ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00K59LUGY | | Amplifier Type | Tube | | Brand | Electro-Harmonix | | Customer Reviews | 5.0 5.0 out of 5 stars (12) | | Enclosure Material | Glass, Metal | | Item Weight | 0.18 Pounds | | Mfr Part Number | 12ay7 | | Model Number | Ele-8702 | | Power Source | Electro | ## Product Details - **Amplifier type:** Tube - **Brand:** Electro-Harmonix - **Item weight:** 0.18 Pounds - **Material:** Glass, Metal - **Power source:** Electro ## Images ![Electro Harmonix 12AY7 Preamp Tube - Image 1](https://m.media-amazon.com/images/I/615mKLOiodL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***2 on 31 May 2016* I'm using the 12AY7 in a Fender Champion 600.

I bought this tube to replace the 12AX7 in V1 on my Orange Dual Terror because I wanted less gain on my fat channel.
