DSL40C Behavior:

For quite some time now, I have been disappointed with the muddiness from the DSL40C. Mine is a brand new 2015 - no modifications such as C-19 - just new tubes (JJ-ECC83-MG / JJ-5751 / JJ-ECC83S / 7025-WA with Electro-Harmonix EL-34 Power Tubes) and a 50 watt WGS Reaper 55Hz speaker.

This amp sat for months covered up and unused. The Blackstar ID-Core 100 is my main recording amp and the Marshall VS-265 has been the main gigging amp.

Recently, I pulled out the DSL40C and messed with it and made an interesting discovery. In 'Lead 1' I can't run the gain over '5' on the dial or it goes muddy. In 'Lead 2' I cannot go over 3 on the dial.

If I observe these rules, the amp actually sounds really good and it super loud and yet surprisingly articulate.

Anyone else find a gain limitation like this??? I was puzzled because I have never experienced this. I can crank the gain on my VS-265 and it never gets muddy. before I sold my 1959 Marshall SLP, it too could be cranked to the max without any muddiness, so i was really surprised by the behavior of this DSL40C.

Thoughts???
 
The JJECC823 in V1 will be your salvation my friend.
I'm surprised you haven't ordered and installed one by now...:run:

I had a long day in the studio yesterday (not the one at home) and then came home and worked all night to complete some of our band's demos....its on my to-do list!!!

If it were me Rob, If I don't like it I would sell it off for a different amp.

Hey! Sorry I couldn't post in detail earlier...I have played both in a studio environment and liked them for classic rock. I feel they are a bit limiting for some other genres but i was impressed with their 'Marshall-esque' tone...just not the price....!!!!

Ok, scratch the Jubilee's.

We'll have to wait and see how the ECC823 works out for you... :whistle:

Hey! After $600.00 for the DSL40C, $200.00 in spare tubes, $250.00 for a Weber attenuator and $125.00 for a custom-made 50watt WGS Reaper 55Hz, what's another $25.00!?!?!?!?!?!?!?!?!?!
 
Mhmm, muddiness at high gain may be caused by a too large coupling capacitor - distorted bass signals cause muddiness.
Or by blocking distortion (which can also be improved cured by a smaller coupling cap although the reason is different).
Or both.

The '82 of the ECC832 can deliver more current than the '83 and thus load the coupling cap faster through its smaller internal resistance. And of course it will not drive the following stage as strong (well, You could use a larger input signal...)

Sounds like this tube might be worth a $25.00 gamble!!!!
