Dumble Acronyms
Hi,
Being new to this forum, the extent of my knowledge of Dumble is the Over-Drive Special.
Can someone tell me what PAB and HRM stand for?
How does a Skyline EQ differ from any other tone stack that Dumble may have used?

Re: Dumble Acronyms
PAB = Pre-Amp Boost/Bypass
HRM = Hot Rubber Monkey / Hot Rodded Marshall / Her Royal Majesty
HRM = Hot Rubber Monkey / Hot Rodded Marshall / Her Royal Majesty
Re: Dumble Acronyms
I believe the skyline is the 250KA mid pot and the .01 mid cap combo

Re: Dumble Acronyms
What I've wondered, being new to the Dumble-clone world... were these designations made up by Dumble, or by the Dumble-clone community?

Given PAB is silk screened on the front panel that's at least one to Mr D.tele_player wrote:What I've wondered, being new to the Dumble-clone world... were these designations made up by Dumble, or by the Dumble-clone community?

Re: Dumble Acronyms
Hot Rubber Monkey is a Dumble Term, as is Skyline EQ, Blues Master, Fat City, precision power section, etc.

I can't remember who posted this at Brown Note forum so I can't give credit due to who it was.
Here are some tone tweaks:
Skyliner tone stack (.01uf/250kA Midrange setup)
- Made the midrange more vocal and opened up the bottom end. The 250kA seems to "push" the mids out there, for a lack of a better word. I run my mids HIGH on my amp, at about 2 o'clock.
"Voice" DPDT switch (single .01uF mid cap or sum .05uf [switch to parallel .01uF with .04uF 6PS cap]
- Just switches between the stock D'Lite .05uF mid cap and the Skyliner .01uF mid cap. FWIW, mine stays in .01uF 100% of the time, even with my Strat.
330pF treble cap
- Brought the frequency knee of the treble control a little lower. High end seems a touch sweeter, particularly in OD. I like the "chirp" this value has in OD.
120pF bright cap
- I felt the 270pF was a little TOO bright, and the 120pF adds a nice sparkle that isn't overbearing. Killer on the cleans. FWIW, I have Bright on 100% of the time in Clean, but I never use it on OD
.05uF/10m pre-OD1 network (as seen on ODS-101-nonHRM schematic)
- Seemed to "round" out the OD a very slight bit. Very subtle, but nice.
Parallel 1K/5W choke replacement resistor (for about 330R net with stock 500R choke replacement)
- Increased headroom, decreased sag. Also removed a touch of nasalness only present at higher volumes.
TAD 6L6-WGCs
- Bumped up the headroom considerably. I tried SED 6L6GCs too, but these TADs are ultra-creamy. Cleans are like walking on clouds.

D'Lite?
So the D'Lite refers to a Dumble inspired 18Watt amp and not to anything that HAD designed?
Re: Dumble Acronyms
Some others:
BM = BluesMaster
PI= Phase inverter
100k Amp = 100k plate resistors in use
OD = overdrive channel
124 = Dumble #124 = de-gooped amp, reasonably well interrogated.
