My thought as well. Just didn’t know if warm up time is an indication of tubes getting ready to die.

No, not at all. It takes them a bit to get ready to do their thing. Some amps may take a little longer than others.

Since the Music Man is my first tube amp, is it normal for it to take 15-30 seconds before you get the volume expected from the settings?

absolutely, the higher the wattage the longer the settling time normally….

no…can you post a pic of the back of the head? curious to see what output tubes you got…

I ordered a set from them and they arrived today. Planning to install on my ebony VP. Does anyone make an EPI TRC with silver logo that fits the VP?

@Engle could probably fulfill your wish.

ready….
Monterey bay is plain awesome….gnarly schedule….Davenport tomorrow, Watsonville Sunday….off to Detroit Monday to fly back and straight to a gig on Wed followed by another one (Pebble Beach) on Thurs…..NUTS…

For me, power tubes is where the magic is at.

The pre-amp was too nasty. Time for more experimentation.

Don’t know about that exact time but a brief warm up period is typical of nearly all tube amps. Most have a standby switch for warm up but I don’t recall if the MM does.

Since you’re new to tube goodness, one absolute rule to follow - never ever under any circumstances ever ever start up that amp unless it’s plugged into a cab, ever! If you fire it up without a cab connection and start playing the bass you’ll likely toast your power transformer, not a cheap fix.

cool….imho…

Love me some Still Corners.

 

[Stealth57]

No, not at all.
Let em warm up.
Once you hit the standby switch, and play the rig.
You'll know if there's a prob somewhere, or not.

Ah, that’s what that switch is for. So, let it warm up in stand by and then throw the switch?

on those amps, allow for a good couple of mins before you flick the standby…..they are true Class B amps and drive the output tubes harder than most conventional (Class AB) amps…..you will extend tube life this way…

It does. Didn’t know what it did first time I powered it up. Thought it died on the way home. Label says stand by is up but it is actually down…no sound

YES! the standby switch applies the amplification voltage to the tubes…when the amp is on with the standby off you heat up the filaments to create the electron “cloud” around the cathode and filament…..turning all on at once from a cold start will strip the cathode of chunks of its thoriated tungsten lining shortening tube life and in higher powered tube amps possibly lead to tube/amp failure….modern Gallium Nitride amps have a similar start up sequence…

prego..

Like I said, SS distortion isn’t usually a sound most chase but in a few circumstances it might be useful. The inverse is ideal, power section distortion which is volume on zero, master on full, power on half and carefully slowly turn the volume knob up while digging in on the strings with the bass on board vol and tone maxed.

More data on the MM amp. $275 including 115 cab.

What? It has to be hot.

Hello all - long time reader, first time poster (on this thread anyways). Anyways, I would like to humbly submit my application to join this elite club. It’s just an Epi IV (bolt on) with Hipshot Tuners but it is new to me. I played it at band rehearsal the other night and fell in love with how it sounded in the context of my band. Definitely a gateway drug - I’m hooked, and want to save up for the Vintage Pro or a Gibson eventually. View attachment 4772059

Congratulations and welcome!

Just rattling around through this.
Take it with a grain of salt.

I bet it is, once it warms up.

My friend/tech just had his Greco Bird pickup re-wound by Novak and he highly recommends his work. He says the rewound pickup is just as aggressive as it was before it went bad.



GRAB IT WITH BOTH HANDS!!!!

Not surprised.
