perfect recreation of the 1970's Dumble overdrive special 50w combo.


This pack contains profiles from an exact recreation of a 1970's 50w Dumble ODS combo. This is the same period amp that David Lindley used with jackson brown 'Running on Empty'. His amp has the classic snakeskin covering, but underneath it's the same amp as this one.
the original combo had an Altec Alnico speaker. This has a celestion high powered Alnico cream which is a great fit for the amp.
The amp was mic'd with a combination of a (£10,000) vintage 1960's U67 serial #116, a classic Sure SM57 and a custom made Ribbon mic similar to the royer 121.

there are 40 profiles in this pack including Studio and DI

There are Clean settings with various pre amp volumes, that will be the number on the profile.
there are some profiles with 'Deep' switch in; DP 'Bright' switch BR.
Then there are 'Overdrive' settings: OD
There are also settings using the FET, this is what David Lindley used as his sound.
the FET is basically a very high quality clean boost, it also adds a little high end too.
there are FET versions of both clean and OD, on clean it makes for a nice SRV strat tone.
there are two 'jazz' setting as well. One is a classic clean deep jazz setting the other is an unusual setting with the 'jazz' and OD.
Also there are the profiles done with the dumbleator, the buffered FX loop which adds another valve stage to the chain and also has bright caps.
I've also done some profiles without the sm57 and re balanced the 67 and ribbon for a different ,softer tone.
There's a lot here and I've tried to give you a really broad spectrum of tones, some of which are not my own personal taste but I'm sure would be great for others.
Most profiles have a studio and a DI profile.


Jo Bonamassa 2018:
finally if you're one of the first 100 I have included a special 'Jo Bonamassa' profile.
after seeing his recent rig rundown(2018) I saw he was using two 50w 80's Dumble's set in the 'Jazz' mode on Overdrive (very unusual) with two fender tweed amps and blending them together using the lehle P split and a chorus.
I have recreated that using my #102 dumble and a newly acquired Dumble tweed amp.
I had to add the chorus, which is very subtle in the FX slot as I couldn't profile two amps with the stereo shift. apart from that though I used the amp settings from the rig run down about 37:02....and the same P split so a pretty convincing recreation of joes current sound.

Any questions feel free to drop me a line on the kemper forum or directly at
