Making an Engater Tourmaster 4212 Sound Great

Hey all,

Shared this over at Tele guitar forum, wanted to share here as well.

A bit about my Egnater Tourmaster 4212, the speaker swap I recently did, and plans for the future with tube exchange. Possibly get some advice as well.

Owning the 4212 for 17 years now, there's was a lot to be happy with. Volume, adjustability with contour, density, presence, and the power grid (so cool and innovative)

There was also some bummers; transformer failed and needed replaced (I was 1 year out of warranty but Egnater still sent me a new one for free, I only paid for install at a local shop), misprint on the back panel for full/half power (not a big deal but I bought this new for $1600 back in 08 as a 16 year old kid and that looks janky).

But mostly, it always sounded a bit harsh to me. I had been way to scared to mess with it when I was younger. Tubes and speakers were expensive and I thought maybe I just needed pedals or to dial it in better.

Now that its an old amp and I'm older and less shy about such things, I decided it was time I make this amp work for me or sell it.

The stock speakers are a pair of Egnater Celestion Elite 80s, which to my understanding are an Egnater spec'd/tweaked version of the Celestion Lead 80s. Something about tighter bottom end.

The benefit of these speakers is almost zero compression and a direct output of whatever is fed into them. They give what they get and are very "pure". However to me this could be harsh. Between my tele with van zandt vintage plus pups, Les Paul classic 1960 with 496r/500t pups, and American deluxe Strat, I found it hard to get a sparkling and smooth or warm tone out of this amp.

Maybe its my technique, maybe its the super hot 500t and very breathy van zandts.

HOWEVER

(IF ALL THAT PRRAMBLE WAS BORING THE NEXT PART IS THE UPGRADE BIT)

Today I installed a Celestion Vintage 30 12 and a Celestion Gold v12, and I have never been happier with a tonal upgrade in my entire guitar picking career, including any pedal/guitar purchase I've made (big statement I know).

I was skeptical that it would make a big enough difference to merit the cost (could buy a decent used amp for the cost of both speakers), but i have rarely been so satisfied with a purchase as this.

The warmth and sweetness this combination brought is astounding. Overdrive feels like warm maple syrup. Overtones are sweeter than honey. Chimes as bright and soft as a well colored piano. (I'm not accepting critism on the descriptors..)

All similes aside, it was a great upgrade for anyone thinking of trying either or both of these speakers.

I will say the vintage 30 would not be my solo pick if I only chose one, I did run it with the elite 80 before swapping in the gold, and I would say it helped with some mid punch and a bit of compression, but the gold is what really brought the warmth. The vintage 30 is great now paired with it as it pushes the mid bite up a bit and rounds the sound out.

With this specific amp one does need to heed the 50 watt limit on the gold v12, as the 4212 allows 100w output. However, I almost never have the power grid set to 100w. Usually for home playing I'm on 10w, and any live playing 50 is plenty.

NOW for future plans.

I'll probably enjoy this for a bit, however, tubes swap easily and I can afford the experiment. So I am thinking of getting a Mullard 12ax7 for the v1 and see what that will do as well.

Open to recommendations for tubes for the v1.

My playing is everything from Skynyrd and Allman slide styles, to Brent Mason country, and all between. Not a lot of metal. I grab my martin and play bluegrass if I want to pick fast.


TLDR; swapped Celestion Elite 80s out for Celestion Gold v12 and Vintage 30. Its an exceptional sounding amp now. Looking for v1 tube slot upgrades to replace the groove tube ecc83s to continue experimenting.

Love to hear from you all, and thanks for reading!

Cheers

Welcome to RT. I'm sure there's people here who have experience with the Egnater Tourmaster and your gear to help you out.

Can you take some pictures of your groove tube ecc83s so we know exactly what you have? Are you interested in new tubes that are in current production or vintage tubes? What are you trying to accomplish by tube rolling?
 
Thanks!

Pictures are attached here.

Since this is my first foray into tube rolling, I'm open to different voicings so I can hear and learn the changes. I've always been a sucker for warmer tones, the warmer the better, and I might go far enough to find a fault down that path, but I figured it would be a place to start.

And I'm sure warmer isnt quite specific enough so to try to put to words I'd say more overdrive than crunch, I really enjoy a good mid voicing if it can be done without too sharp of high mid harshness.

I'm open to current production, reissue, and I'm not against nos but I probably wont spend $100+ on a tube in the near future (which i know will probably rule out most worthy nos options)

The egnater has 8 ecc83s preamp tubes. V1 is input gain and will make the most change. I also might swap the v3 spot which controls second and third gain stages for the clean/vintage channels, which is what I use mostly.

It would be nice to get a warmer drive out of the vintage channels without a pedal. I like to use my od pedals to boost and slightly shape the natural overdrive of an amp rather than produce the entirety of the drive sound itself.

Hope this clarifies. Thanks!

Thank you very much for the picture. That's a JJ ECC83S that has been relabeled by Groove Tubes so you're familiar with the sound of JJ. That leaves you with current production tubes from companies like New Sensor, Psvane and Shuguang that you might not have tried yet.

There's a lot of great sounding tubes for less than $100. From what you've told me I'd recommend Ken-Rad and Blackburn Mullard the most.

The first two versions of the Ken-Rad are commonly known as carbon and pewter plate from left to right. I'd look at one of those but the pewter plate in the middle is usually the most affordable, best testing and easiest to acquire.

There's a few versions of the Blackburn Mullard long plate but I think you'd prefer a Blackburn I61 or I63 short plate the most. The I61 has copper rods and the I63 has nickel rods. Look for the B code BXX or BXXX and the I61 or I63 etched into the glass to identify a Blackburn Mullard.

Lots of great American black plate 12AX7 or European ECC83s to try but I think you'd like those two best from what you've told me. The Blackburn Mullard sounds closest to what you're after but the Blackburn Mullard and Ken-Rad are better together than either one separately IMO.

This is super helpful! Thank you for this detailed reply.

I had been searching around for Mullards but the only thing I could find under $100 was reissues. Most Blackburns I found were over $200. Is it possible I'm looking in the wrong places?

Ebay or reverb are about the safest. It can take time searching for the right tube at a good price. Mullard ecc83 I61 I63 or some combination in a search but you have to look carefully at the codes, construction and measurements of the tube. BXX or BXXXX and I61 or I63 in the etching for Mullard.

I quickly looked on ebay and I don't want to promise the world in terms of their condition but these tubes seemed good quality and fairly priced.

This is astronomically helpful. It's always intimidating diving into a new world of parts and especially old stock.

Thanks a lot for the info. I'll check some of these out.

Cheers!
