What is the year difference between Mk1 and Mk2?
@JIO
To remove the chassis from the case, locate the four plastic plugs on the sides of the case and remove them.
A standard number two Phillips will get the 4 screws out and then you can slide the whole chassis out. Goes back the same way with a little wiggle.
Sorry, I don't know the years of production. The LB30 schematic is dated 2010 and the earliest mention I can find is Dec 2009. My understanding is at some point there was legal action in regards to the name Little Bastard...probably some sort of cease and desist from the James Dean estate.
So the amp was given new graphics and remade as the CTM30. I believe Ashdown claimed it was exactly the same circuit, but I am not sure if this is 100% accurate as the CTM30 photos I have seen show an added power supply choke on top of the chassis. The original LB30 uses a pair of 1K 5W resistors rather than a choke.
AFAIK the LB30 Mk2 from the custom shop are sort of recreations. Basically Ashdown had a bunch of different parts left over from the original production run of various amps. So they made small batches of amps to use up those extra parts, and fabricated whatever was required to make them complete. In some instances I think they combined various assemblies from different models to make complete amps. I suspect with the LB30, the left over part was simply the chrome front panel. I believe this panel is identical between the Mk1 and Mk2, but the red plastic insert(s) that have the labels for the controls is obviously different. I believe the chassis is different as well. I am certain the main circuit boards and headcase are different. The UK Custom Shop circuit board is labeled Mk2. The Mk2 headcase is slightly smaller and is not vented.
The serial for my Mk2 ends in "-12-20," which I suspect is the month and year of assembly. AFAIK they listed these amps on their "Last Chance" page and then built them when one was ordered. So the Mk2s were available for awhile.
I use the DI on my CTM-30 all the time - usually to the PA, have also tried it for recording. It works really great for both, capturing the sound of a slightly cranked tube amp. There's no speaker simulation on the DI, though, so it may want a little EQ shaping in the mix (especially on recordings).Searched the thread for DI and only got my own post as a hit . What are the experiences with the DI ? Curious on the opinions!
Just realized that the latest version of the Ashdown CTM-15 also has a built-in power soak, so that might be worth looking into.
Just received the LB30 - learned it is actually NOS, original tagger still attached.(I unraveled it instead of cutting it for prominence-sake
) It's been in a music store in Santa Cruz since new, of which the proprietor Dave was an Ashdown dealer.
This! A tiny bit of high- and low pass filter and you should be good to go.

Haha, it better not be clean! A little hair, a little dirt, and some crunchy bitsDon't expect it to be clean though![]()
I just pulled the trigger on this 4ohm/400watt EICH 1x15XS cab for the LB30. I wanted a vertical orientation cab and liked its retro vibe. (not a fan of heavy 1x15 cubes) I think it will be perfect for use in our rehearsal space.

Very cool, I am running a LB30 through a TecAmp M210. It’s my favorite cab to run with it.I just pulled the trigger on this 4ohm/400watt EICH 1x15XS cab for the LB30.

I’ve actually found the CTM -30 to be much cleaner than I thought it would be from reading this thread. At the volume I will be using it for acoustic work it is completely clean. Haven’t opened it up more than half yet to see what volume the dirt begins …. No idea if I can use it for electric material also. But to be honest much more clean headroom than I thought! Using through these old trace cabs. larger cabs look a little silly to me and the really small stuff has too much overhangThis! A tiny bit of high- and low pass filter and you should be good to go.
