The amp is based on the ODS 101 schem non HRM. I did however build in a Dumbleator with a switch to remove it from the path. It is built in to silver faced Bassman head on a turret board. The guitar is an American standard Strat with hi output noiseless pickups. While it does not have the "grail" sound, it is a good sounding amp regardless. The effect is from the loop using an old Lexicon Alex....4-12 Marshall cab with G12T-75s into a mic and recorded on a cheap 4 track casette recorder. No other effects or editing. Complete with bloopers. I do not play with a pick.
To all who have contributed so much to this board with your knowledge and advice, thank you.
An mp3 is located at http://briefcase.yahoo.com/roknroll50 under "clone".
Hope you like it.
PS
to those of you who are worried about whether to build in a Dlator or not, clone7.mp3 is a clean chord vamp with no effects Dlator off, repeated with each pickup combination and then repeated with the Dlator on. I really don't hear any difference in tone. Just my 2 cents.

Re: ODS 101 fired up
Sounds great! These amps like humbuckers, IMHO, so give that a try before you discount your amp in any way! 
How does your clean channel sound?

Clean channel mp3 is now uploaded. Just light finger picking just to hear what the amp sounds like.

Re: ODS 101 fired up
I think it sounds great. Nice job!
Re: ODS 101 fired up
The amp sound "dumble-y" to me,..I just finished a D'Lite and it has that sustain and nice high harmonic content in both the clean and OD modes that I hear on your clips.
I think the "grail" sounds most of us are familiar with have used guitars with humbuckers, or a boost with single coils. Try some "Robin" licks with a little clean boost.
And the picking is impressive! Nice job all around.

Re: ODS 101 fired up
Again thanks for the kind words. I have tried it with Hums, it sounds good but not Robin Tone. Maybe a hollow body with hums would help. I'll record this weekend and let you guys be the judge. After 40 years of LOUD, my ears are shot anyway.

Re: ODS 101 fired up
Great sounding all around.
What type tube are you using for the Dlator and what are your plate voltages on that tube?
Also, the Lexicon is very lush sounding. I assume it is digital but it sounds analog. I have a GT-3 I use for delay but it does not sound as fat as your Lex. I would love to lose the GT-3 but I need delay and verb.

humbucker tone posted
Dlator tube is 12at7.
No matter how I try I can't seem to dial out the high midrange low treble fizziness or grit in the background. Also the neck pickup has a tubby sound that I can't seem to dial out. The recording was done with the bass control near zero.
Already changed clean2 bipass cap to 1uf. Still tubby.
Any help or suggestions would be appreciated.
Thanks

Re: ODS 101 fired up
Try replacing all silver mica caps with ceramic. Do not use over 10pf on the global master. Replace all signal resistors with carbon film, except the cathodes and plates. Use RN65 on the plates.
No Dumble I have ever seen had 1uf on CL2. Doesn't sound very good to me. You may want to try a smaller CL2 coupler (.02-.033) That may clean things up.
Nice playing btw.

Re: ODS 101 fired up
Will try your suggestions over the next few days. Thank you for your input and thanks for the compliment considering I have listened to your clips in awe and drool over the last many months.dogears wrote:Try replacing all silver mica caps with ceramic.

Changed over to RN65 resistors and put back 5uf cathode bipass cap on cl2. While I have to admit the lead tones sing and are quite amazing the neck tones from the A and E string are still muddy. when the lead pickup is at at it's best, the neck pickup is at it's worst. Even when bringing down overall distortion levels the lower strings are never tight. The D, G B and high E strings sound great on the neck pu but below that is where the fartiness begins. Clean, the amp sounds wonderful, and through the effects loop it's magic.
Thanks for your input.

Re: Advice appreciated
Dogears will shoot me for this comment, but I think your problem can be cleared up with a slightly larger bright cap on the master volume. I went up to a 22pF then a 39pF and the most dramatic change was on the flubby low notes. It tightened them up considerably. For one, dogears likes the bridge PU for OD, I like all settings and I like transparency, letting the charactor of the guitar come through.roknroll wrote:Dogears

Note, this cap must be ceramic, silver mica will sound like you put a blanket over the speakers.
Which master volume
Bob
The amp is based on the Amp Garage schem labeled ODS-101. It contains 2 master volumes. Which one are you referring to?
Thanks

Re: Which master volume
I think your issue is with the OD section right? Then it's the OD master.roknroll wrote:Bob
