"The first Chinese tube amp from Fender was/is the Champion 600. The original 1950’s 5B1 version was a simple as simple gets: two tubes plus a tube rectifier. One-half of a dual-triode as a preamp stage, the second half as a driver, and a single power tube as Class A power amp, with just a couple of resistors and caps to make it all work.

This new version keeps its two-tone dress coat on, but inside, it’s a totally different animal, and the sound bears this out. It is not a BAD amp, but somewhat anemic as compared to the original. The main reason is the trick borrowed from the 6G6-B Bassman of using a preset tone stack internally to shape the typical “scooped” Fender tone. Tone stacks rob gain, and lots of it. This also translates into a stiffer feel. In larger amps with tone stacks, the gain is recovered with an extra tube stage, but not here. There is also no “sag” due to the solid-state rectifier. So, what starts out as a good idea falls short for many players, including yours truly. I like amps to have balls and to “squeeze” a bit, and this mod will do the trick. If you own one of these and are looking for righteous Rev. Billy Gibbons or Keef tones, this mod is for you.

Let’s assume everything is golden and it works. Just turn this baby up to “12” (that’s one more than Spinal Tap) and ROCK! All pickups sound great with this mod, but PAF-style humbuckers and P-90’s are a really treat for the ear. My favorite test? Tune to open “G”, get the capo out, and pretend I’m Keith, minus the 40+ years of drug abuse, of course. I also have yet to climb a coconut tree."

I also included a switch which selects between the stock mid-range resistor in the tone stack and a "thick" option - which provides a slight volume boost and enhanced mid range. This allows you the ability to "dial in" your tone for various guitars and amps.

I know what I am doing and my work is clean and correct. I've performed these modifications / upgrades to dozens of Fender Champion 600 amplifiers and its "sister amp" - the Gretsch G5222 Electromatic. I know there are many "basement amp techs" modifying these low wattage tube amplifiers. I am meticulous in my work and the quality speaks for itself. Check out the included photo of the modified circuit board. Still not convinced? I guarantee my work until the end of time! That's right - if you should ever encounter an issue with the craftsmanship on my modifications or repairs, I will repair or replace free of charge! Bid with confidence!

These are fantastic upgrades to this amplifier! Not only does it blow away the stock model but other amplifiers costing many times more! The sound is clear, "punchy" and defined. It can go from rich, defined clean tones at lower volume to snarling overdrive when turned to "12" (yes, the volume goes to 12!)

Here's a list of the modifications and upgrades:

• Replaced the "blanket-like" grill cloth with material from Mojotone. The oxblood color matches the Fender badge exactly!

• Upgraded cheap Chinese 12AX7 preamp and 6V6 power tubes with higher quality replacements (JJ and Tung Sol).

• Replaced the stock six inch speaker with a Jensen ceramic Mod.

• Volume pot and all input jacks cleaned.

• Replaced stock knob.

• Includes custom Alchemy Audio amp plate and bonus goodies!
