Intro and Liverpool Build

[fishy]

Congrats on your build....

[lions den]

Thanks. I notice ther are a few members in the Phoenix area, may have to arrange a Tonefest party

Awesome Sean,You gotta complete the set. your doing great!!!!!

[lions den]

Ok wanted to put together a clip to show the clean to mean of the Liverpool project. With effects to fill things out Done quickly on an M-Audio Micro-Track.

Guitar is a PRS Singlecut with Humbuckers that are splittable......

Will also post some final pics, just working on some faceplate details with Mike Great cab by the way....

I have a question about a phasy/fuzzy artifact I'm hearing on the LP #2 clip at around 17 seconds and 27-29 seconds. I've heard this before on old Marshalls and was told it's part of the vibe of the amp.

It's very pronounced on the neck pickup and bass notes......
Is this something that can be tweaked out?
Any suggestions on what to look for?

Already ordered my Rocket kit from RJ so I can complete the trilogy
thanks,
sean

Clip 1 was sweet. Sounded great.

Clip 2 I don't have a LP so I don't know what it is supposed to sound like but my opinion is it seemed like the recording in several spots immediately clipped in volume, which might be a mic issue? Didn't seem to happen with clip 1. As for the sound you're talking about (fizz) seems like there is some dampening of the note preventing it from sustaining longer. I heard this on clip 1 at 2:10 I think, as well, but I liked it in the recording... I don't think that is normal behavior but I don't have a liverpool.

Wow,I love the clip 1,absolutly awesome!!!!.What did you use to get that reverb delay,Please tell me I can buy one pedal that does that spookey
lush tone. Amp sounds killer Sean,Mikey

Sean,

Gotta say, to me, Clip one is one of the best examples of LP tone I have heard - fantastic clean to very compressed mean.

About the swirl in clip 2. I am at work and can't listen in full detail. Do you have any grid stop resistors on the preamp tubes? When I have run into "swirl" issues in the past it was mostly around the PI. You may have to play with the PI input cap value, or place a 220k resistor right after the input cap to the 1M grid leak ala concorde (the grid will be fed from the junction of the 220k and 1M , or add a small grid stop r, or output coupling cap value change or even change the B+3 filter cap value. Also try lowering your neck pickup a little away from the strings (try this first). All of this will change the dynamics of the amp....

Maybe Jana, a marshall expert, will chime in about "swirl"???

Maybe someone with better speakers and time can hear it more clearly....

Once again, sounds fantastic.

Everyone, Thanks for the feedback on the clips.

John, I built this per the layout schematic in the TW files section so no extra grid stoppers or altered values. Those suggestions are exactly what I'm looking for to chase this down a bit. At times it's a cool effect, but I may want to temper it down just a bit.

This is my first build and will all be experimentation from here so I'm open to all suggestions.

Mike, I'm using a wet/dry setup for effects so there is always a direct amp sound. There are actually two pedals going on. One is an Eventide TimeFactor delay. That is providing the pad-type moving drone sound using a repeat function on the pedal. There is also another delay for the guitar playing over the pads. I'm using an Eventide PitchFactor for that but any stock delay can work.

I may try to re-record today and make sure I don't get any overloads on the recorder, it was pretty loud

Thanks for the help.

Clip 1 is killer.
Not sure what to make of clip 2 other than what has been said..

Let me know if you want to compare against another build. I'm just down the road.

[lions den]

Fishy,
Thanks I may take you up on that offer to compare sounds and layouts.
Would be fun to hear another build in person.

Clip 1 is killer.

Exactly!!! I must have listened to that 10 times already

Sean, If you are going by the schematic "Based on the M Kryger schematic and Liverpool86 photo", may I suggest that #1, you lower your neck pick up slightly and #2, what value of R7 are you using. IF it is 150k, you may wish to try lowering it before any of the PI mods I suggested. Reading back in your posts you mention that this amps likes the strat better, I am guessing that you have some blocking distortion going on. A few grid stops and playing with R7 may just tweak it into line.

Even simpler, maybe try a 12at7 in the PI or other....

Good luck, and once again the cello tones one that first clip after 2 min are haunting.

John

[lions den]

John, yes R7 is a 150K and I noticed its one labeled as being anything from 33k to 150k depending on tone desires. I'll start there and see how things go.

Thanks,
Sean

Great amp!

Let me know, that would be a blast.

+1 on R7 C8......
Playing around with R7 and C8 can prove quite enlightning. You can just clip them in. Dropping the 150k down to 68k and doubling C8 will still have some serious gain on tap. That said, my pool has stock values for R7 C8.

I haven't played much with the PI tube but have liked a 5751 in V1. The plate resistance is comparable to the 12AX7 so the effect is just to drop the gain. If you have one, its the easiest thing you can do....

[lions den]

What are the stock values for R7/C8? I see ranges on the schematic.
Thanks
Sean
