Email Nik from the Ceriatone site.. I`m sure the Dumble clones take around 6 weeks. When my OTS was built May 2012  the wait time was 6 weeks, although the amp arrived on my doorstep within 4 weeks..!
Nik is always really good to deal with and replies to emails promptly.
I have a 100watt OTS combo with 1/2 power switch added.. this mod was about another $15.. and a great option to have.
If you`re used to Blaceface Fenders, i would run a reverb unit in the loop of the Ceriatone.
There are a few reverb units that are highly compatible with the high impedance of the Dumble spec effects loop.
My TC Electronic Nova reverb is perfect.. although the Fuchs Verbrator looks interesting as well..!
Compared to Blackface amps, i feel the Dumble clones are a bit more versatile & have the mini toggle switches for Deep, Rock, Jazz settings etc.
The OTS has a slightly pronounced midrange frequency compared to Blackface Fenders.. which in my opinion is a good thing.
The clean channel on the OTS is very nice too... not to mention the OD channel.
New Dumble clone with brand spanking new components.. easy to service or mod.
The Ceriatone Dumble clones have bias probe points & bias pot mounted externally.. making adjustments easy.
