I do not want to use the split mode again. Sounds like it could damage the Mark V output transformer.

I noticed the same thing with Mark V 90 W head.I have Sundown A50 head, Boogie Mark V head, Mesa three-quarter 4x12 cabinet and Mesa 2x12 (C90/EVM12) metal grill cabinet. Mark V 4 ohm output to left side 4 ohm input of 4x12 cabinet A50 4 ohm output to right side 4 ohm input of 4x12 cabinet...

My previous amp was Mark III, so it did not take long to get good sounds from Mark V 90 W. Doug West's video with 4x12 closed back V30was helpful. But my cabinet is three quarter 4xC90. So my settings must have less presence but more bass than Doug West's settings. I have tried every possible...

I have adjusted Mark V Crunch mode with my 12 string Stratocaster. It has 3 EMG S pickups. That is very much like 70's Alex Lifeson sound. Those settings are terrible with my Flaxwood Voima's Seymour Duncan SH-14 bridge pickup Then I decided to try Edge Mode with Flaxwood Voima. I dropped...

It looks like reverb is designed to have cut when changing channels. https://forum.grailtone.com/viewtopic.php?f=33&t=73186 I don't mind that. This case is closed.

https://forum.grailtone.com/viewtopic.php?f=33&t=85312&p=524667&hilit=reverb#p524667 Here some other user said the same. And one user suggested, that reverb behaves like that when channels have different wattages.

Hello! I have small problem with reverb. It is so small, that it took almost one year until I noticed the problem! But first I have to explain what is my system. https://drive.google.com/file/d/1DCq1V6erWcF7qXlA7Ns78wJA8UbCjOTj/view...

I have seen couple of 2009 Mark V Export amps. They all have "Variac" label.

I changed the V1 preamp tube (put that huge cover back also) and it was not easy. After that only hum could be heard from the speaker. I removed the V1 tube and it looked fine. I put it back (but not that huge cover) and still no sound. I removed the chassis and it is ridiculous how difficult...

I ordered EM Custom Mark V midi interface. No delay when changing channels. Highly recommended!

I found the 12 V pin. When back plate chan 1/chan 2/chan 3/Footswitch rotary switch is on chan 3, I could change solo, FX loop, EQ, reverb, mute on or off by shorting the pins with ground. But I could not change the channel. So you are right. Channel changing is digital. I will probably buy EM...

Hello! I believe that Mark V 90 W 8 pin din connector is just 7 on/off connectors and power for footswitch. So the pins should be: Channel 2, Channel 3, Reverb, Mute, FX loop, Solo and EQ. The ground is needed of course. So I have 8 pin din connector and I am planning to build a connector box...

My previous amp was Mark III combo with 1x12 EVM12L Thiele cabinet. My second amp is Sundown A50 head with Mesa Boogie 2x12 metal grill cabinet. I bought Mark V 90W head and I need some new cabinet. Mesa Boogie 2x12 metal grill cabinet (C90 and EVM12L) is great with Mark V but those are hard to...

Yes I follow. I have played with looper with Mark III. It's a pity, if it's not possible to play over the top of the recorded loop with a different channel.

This happens also when the reverb tank cable is loose. It happened with Mark III many years ago and with Mark V last week.

I tested it again. When only Boss DD-5 was connected, there was only slight treble loss send level at noon. I could not hear any treble loss, when Send level was At 11 o'clock. When I added Boss CE-2, I heard bigger treble loss. Finally I tried to connect all the effects and send level was at 7...

Those images vanished.There were server problems. New images can not be uploaded.

Thanks for the reply. At least one of my Boss effects (DD-5) has the -20 dBu input and output level. There is no information about nominal input and output levels for my other Boss effects (HF-2, DM-2, CE-2, HR-2). I must test the Mark V with just Boss DD-5 Digital Delay connected to FX loop. FX...

I tried Mark V with my Boss effects connected to the FX loop. With Mark III there is no treble loss, but with Mark V I can hear a significant treble loss. Channel 1 fat mode channel 2 crunch mode: Slight treble loss which can be solved by presence increase Channel 3 Mark IIC+ mode Huge...

It was Albert Jarvinen: http://www.youtube.com/watch?v=6PJEU8gLMo4&feature=related In this playback performance you can see 1x15 Mark IIB combo. The record was released in 1980.
