maybe do an episode on why a tube amp goes so much harder at the given wattage rating than solid state (both are analog, this is not an analog vs digital argument, I love my Roland JC200 and you can't have it) especially at smaller wattages (I have a 40W Acoustic brand bass amp that can't push as well as my tiny 5W tube head). Yes, a JC200 and it hardly ever gets used because JC200 lol

The MT15 benefits massively from having an EQ in the loop. That gain is just so fucking THIIIIIIICC!

These things in stock form put out 27w or so. There’s a video of a guy who put it on a scope and measured the output. They’re louder than hell. As loud as my 50w amps. And you could put a 50w output transformer in the mt15, but in order for it to put out 50w you’d likely need to change the power transformer and change dropping resistors in the B+ circuit + a few other things with biasing to actually get the tubes to dissipate that much output for the 50w output transformer. Theoretically two 6L6s can put out 60w at max dissipation but the amp isn’t actually allowing for that and even then, you’re going to be running them fairly hot to get that 50w.

@@K707OR30 Sounds like the hassle is far outweighed by getting a decent 100w tube high gain amp and probably around the same cost :)

I own one of these and have a few notes for you based on my years of ownership & learning about my first tube amp. 1. Someone tested the MT15's true power output and measured it around the 25 watt mark. That's part of why it hits the way it does along with all of the other engineering goodness. 2. The lead channel volume pot has a weird taper to it. That's why the gain channel is so immediately loud then it just gets "squishy" past noon. They designed the head that way and I'll never forgive that decision. I'd prefer a more standard volume sweep. 3. I know the head was designed around use with a V30 speaker, but I feel a little more Death Metal-y when i play it through my G12K-100 speaker. If you own a K100, could we get a YT Short comparison between a V30 & K100 with the amp dialed best for both sounds? 4. A Guptech PDEQ pedal in the loop is the simplest way to get the Depth & Presence where you want them. However, I usually use my ten band MXR to add subtle depth and to dip 500hz a bit to prevent "woody" low mids. Thanks for being a fun person and all you do.

I paired it with DV-77. Such a Nice amp and speaker pair.

Proud owner of a 6L6 MT-15... Nice work, TD....

underrated YT musician. great content.

Owned two MT15 (6L6 and 5881) and two Archons (both models). The Archon USA is the better amp and you can play it next to a Dual Rec or 5150 without a problem. Sounds fantastic. The MkII wasn’t as good but it’s still a good amp. It’s drier and more Rectifier like IMO and the difference in price vs the MT15 is like $100USD (the MT15 is just a tweaked Archon at the end of the day). The MT15 is seriously loud, but the loops are often terrible and the amps often just hum annoyingly the moment you turn them on. The Archons are dead silent and the loops are A1. Any ‘15w’ amp produces like 25 watts. Get a Vox AC15 or Tiny Terror and scope them. They’ll hit 25w driven just like the MT15. The difference is that the MT15 has girth at those volumes because of the bigger OT and big bottle tubes. If you install a bigger PT, you reportedly get around 30 odd watts ‘clean’. Doug Sewell states that the MT puts out 16w ‘clean’. A 50w amp puts out around 50w clean also and like 70-80w driven so you do get more clean headroom. The reality of a 50w vs 15w amp is that you’re only talking 4 or 5dB difference. It’s not much and the vast majority of the time you’re not going to be playing at 115dB. It’s just nice having the extra girth if the weight isn’t a factor.

Great and honest vid. You really went an extra mile to show this amp. I have it like for 3,5 years or sth. And it is great. I had no problem to be heard on the concerts in different spaces (without mic-ing it into PA). Boss EQ in the loop is the way to go. You can add some lows (120 Hz) and cut 60 Hz for tightness, -3 db at 800 Hz to get rid of the honk in mids (and to compensate set mids and treble at 2-3 o'clock). And You can add 3,2 kHz of even 6,4 kHz for that sizzle. I like Your vids and personality. Keep it that way \m/

I just got mine last week. I was having trouble with my Blackstar ht 40. I like its sound, but it gives me trouble sometimes. The MT-15 is an absolute animal, Im loving it. I have an old Peavey cab from the 80's, 4×12. Celestion g12-k 75's. I run it at the half power, 7 watts and it still roars. I was curious before buying it if it could push a 4×12, that was quickly answered.

I would love to put this against the equivalent Wang's amp. I have a little 5W Wang's and it pushes way harder than it should. They are super fun and surprisingly well made.

I walked into my local guitar sphincter and could hear some chugging from behind the used area wall and i knew what amps had been there. I thought it was the EVH 100 creme but turn the corner and it was this MT15.

Great vid! I own 2 of these and never been let down by them. Cheers 🤘🏽😈🤘🏽

With silent and low volume stages and most bands running everything through a PA either mic’d amps or line out direct a 15 to 20 watt tube amp with a good 2x12 or 4x12 is plenty loud enough unless you’re in a situation where for some reason or another you need a “spunky” clean sound or prefer more headroom than a 20 Watt amp can deliver. I started playing in the 90s when we all thought we needed 100 watt heads and at least a 4x12 to get by but preferably a full stack. I played with a drummer that played so loud and that was the only way he could play he hit so hard and little Dynamics but it was cool because we were playing thrash and some nu metal so it worked. I had a 50 watt jcm800 2x12 combo and a Crate 4x10 cab (and yes that 4x10 sounded awesome even in metal application don’t sleep on 10 in speakers metal heads) anyway the other guitarist had a SS 100 watt Dean Markley and a Carvin 4x12 he preferred darker and more bass heavy tones, and I always leaned towards brighter Marshall tones. I don’t think I ever got the 50 watt 800 past 5 on the master and at that point his the other guitar vanished and you heard cymbals, snare, kick and my guitar. It was the 90s so of course we scooped out the miss and took up all the frequencies our bass player should’ve been handling he had a 300 watt fender but most of the time you couldn’t hear him, we played in a garden shed at our drummers house and were way too loud but we had a blast

Mt15 is still my favorite guitar amp...I just love it

Could you test the Stagg 250GARH? I’m very curious about that amp. A friend of mine had the 30 watt combo years ago, and as far as I remember it was pretty cool, so 250 watts of coolness would be.. well.. pretty damn cool.

The MT15 is a stupid little amp. I love my 5881 loaded example. It always impresses anyone who plays through it. And it definitely has zero issue getting to gigging volume. I think the effects loop is still too touchy, though. It seems like the 12ax7 used for the loop is too hot. A lower gain pre-amp tube would probably calm it down a little.

Guitarist in my cover band runs one of these thru an Orange 4x12 w/ V30s, and it is OBSCENELY loud. Half power is good enough for an entire band at practice volume, not just a drummer. I'm using a 500W Terror Bass head with a Barefaced Six10 cab, and I'm not sure who would win a full-on decibel war.
