What are the best tubes for Fender Amps?
They have been behind countless classic tracks and dominated the market with their versatile range of electric guitar tones. From smooth jazz to hard rock, Fender amplifiers are always a sure bet for awesome guitar tone.
Yet wait, you know all this. You are reading this because you are already in love your Fender amp, you take it everywhere and you want it to perform to its absolute best.
Here is Fuzz Audio’s list (by era) of vintage valves that will help you get that extra 10% of warm tube goodness of out your Fender tone machine.
RCA is King, GE is Queen
When it comes to vintage Fender amps and really any classic USA guitar circuit, RCA is always the first brand that should come to mind. This is because for any given Fender amp made prior to 1965 there is an 80+% chance your amp originally came stock with RCA tubes.
Because Fender relied heavily on the use of RCA tubes up until about 1965, they should always be considered when upgrading tubes in a Fender amp or restoring an amp back to original condition.
However, that being said, other USA manufactures should not be overlooked.
Remember how we said, “80+% chance your amp originally came stock with RCA tubes?” Well, the other 15-20% would be found with GE tubes. GE 12AX7s in particular are a great budget valve to get your amp running optimally without burning a hole in your wallet.
The Best Tubes for Fender Amps by Era
Tweed Era (1948-1960)
Single speaker tweed amps deserve long plate preamp tubes. If you play with lots of distortion, fuzz or like lots of warmth; black plates are by far the best tubes for tweed Fender amps.
Stock tubes for early tweed Fender amps:
Our optimal Tweed Champ set:
Black Plate 12AX7
RCA 6V6GT (smoked)
RCA or Tung-Sol 5Y3GT
Back and Brownface Era (1960-1967)
As amps started to get bigger, tube plates became smaller to compensate for “noise floor” with the larger Fender amps of the 60’s.
If you have a blackface amp with one speaker, long plate preamp tubes are still the way to go.
On the other hand, if your amp has more than one speaker, and you want your amplifier to be quiet, you may want to look at tubes like the 12AX7A or 7025. Both RCA and GE have great versions of these tubes. For power tubes, hands down best performers are RCA black plates.
Stock tubes for Blackface Fender amps:
Our optimal Blackface Twin Reverb set:
4 RCA 7025
2 RCA 12AT7 Black Plate
4 RCA Black Plate 6L6GC
Silverface to Modern Era (1967 - Present)
Early Silverface amps would have been found with the last batches of the classic RCA tubes of the Blackface Era. Yet by 1970 the glory days of RCA were over, and we see Fender start to plug in Sylvania/Philips Preamp tubes, along with GE pre and power tubes. These tubes are typically branded “Fender” and sound less warm than earlier versions.
Thus, in our opinion the best vacuum tubes for Fender amps were made pre 1970, and because of this, we are left with the options already mentioned if you are chasing legendary tone.
If you are trying to return your Silverface amp back to 100% stock components you would have several options, as Fender was inconsistent with the tubes they used in this era.
Stock tubes for early Silverface (1967-70):
RCA/GE 12AX7A or 7025
Stock tubes for post 1970 Silverface:
Sylvania/Philips (USA) Preamp Tubes (Sometimes Fender Branded)
GE 12AX7A (Fender Branded)
Power tubes: USA or even JAPANESE
At Fuzz Audio, all vintage/NOS vacuum tubes purchased through our website are guaranteed for one year from purchase date. We accept returns for tubes going noisy, losing output/performance prematurely, and of course losing function all together. (Read about power tubes below).
We will not cover damage from red plating neglect, glass breakage of any kind, loose bases, or other obvious faults that are due to neglect, rough handling or egregious constant use.
This policy is meant to protect the buyer from having a tube go out on them prematurely from a flaw we missed. Tubes, especially preamp tubes, should last half a lifetime, and well beyond a year, so we want to guarantee each customer that you get a tube that will last.
For power tubes, although we will honor any faults mentioned above, we will not accept a return for a power tube that has obviously been used for 6+ hours a day for every day of the year for one year. Power tubes that have clearly been used beyond their normal wear point will not be accepted.
