I think your friend will be able to do this without any trouble. I'm sure he knows scads more than I do, and I did mine myself. As long as he can solder and understands the basics he ought to be fine.

I got the Reeder mod done. My (much more mechanically inclined) friend did it & foot switchable gain in about 45 minutes. I have only had about 15 minutes to play the amp since, but my first reaction is WOW! It Truly is identical to Channel one. What I didn't expect (but should have) was that there is alot more volume to channel 2 now since I like the gain around 2:30.

Now, I was not dissatisfied with channel 2 before the mod. I liked it quite a bit. I did it more out of curiosity. While I definitely need to play with it more than I have, my first impressions are that I won't go back.

Thanks Charles Reeder.

I finally got around to performing the Reeder Channel 2 pot swap. I recorded a quick riff from Steely Dan's "Midnight Cruiser", and I really like what this mod does. To my ears, it adds clarity and definition without losing the fat boogie sustain that made me like the Lone Star to begin with. Not sure if this camcorder mic does it justice. In person, the additional presence and top-end are more prominent, than in the vid. Also, this is recorded at bedroom levels ... I'll report back after I gig with my new Reeder tone. Thanks CR!

my pleasure, DJW ... do you think the camcorder captured a significant difference?

The difference I heard was fairly subtle... more subtle than what I hear in my own environment. But there obviously could be many reasons for this -- camcorder recording being what it is, your particular amp settings, etc. (I wished I could see your settings better in the clip, by the way) However, the way you describe your findings is right in line with how I hear it: the tone still has a lot of girth and fatness, but a more pronounced high-end edge and clarity. Great playing too, by the way!

Thanks I was really just fishing for compliments ... "good answer" :)

but seriously - the camera's compression is hiding some of the clarity found from the ReederMod. I played the amp in a larger room today, and cranked it up a bit - MUCH more noticeable and I liked what I heard.

I just did the mod last weekend. Before, it sounded like the speaker had the proverbial wet blanket over it. After the mod, it sounds cleaner and brighter; not nearly as muddy as it was before.

It was easy to do as well. If you know how to solder, then it's a piece of cake.

Hi all!
My first post, but i've been enjoying reading this forum for about a month. I'm very grateful for the fantastic expertise shared here! Thanks to each of you for providing an absolute wealth of info and ideas. Very smart crew here!

Since i'm not very tech savvy i had a real tech do the ch2 drive ftswitch mod-very cool! i'm still experimenting with how to balance the 2 levels...

Still undecided re reeder vol pot mod.
is ch2 still higher gain than ch1 after the mod? or are they identical sounding?
to my ears ch2 can be a bit 'nasally'-is that the 'murky/wet blanket' folks say gets removed by the mod?

an observation: while experimenting, i maxed the gains of both ch1&2 (tone settings identical) and got identical sound w comparable vol levels by turning the ch1 a bit lower than ch2. so, maxing out the gains understandably mitigated the pot taper differences. but it was surprising to me that ch1 is louder than ch2 when the masters are matched!
any thoughts?

btw ch1 sounded great with that extreme setting:
gain: max
treble: 12 noon
mid: 9:00
bass: 12:00
pres: 3:00
master: 12:00
power: 5watts
output: 11:00
using an es-333 (same as es-335 w less fancy cosmetics) the sound was full and rich with alot of overdrive, but turning down gtr pots yielded beautiful cleaner sound.

thanks again to all of you!
Dangit!

hi all

another question re reeder mod#1:
i saw a post that complained that the mod made ch2 master "hair-trigger".
this kind of makes sense given that the taper is different.
the stock configuration is easy to fine control the volume of ch2.
does this fine control get lessened by switching pots?
if so, then perhaps leaving ch2 master pot#581739 where it is and just replacing ch2 gain pot#591047 with another pot#581739 purchased from mesa would open the sound up but still allow fine control of ch2?
thoughts?

thanks!
Dangit!

Hey Dangit, those are good questions. It's not surprising that the channels sound the same with those controls maxed. The only differences between the channels (when the drive switch is disengaged) is the tapers between those pots, so when they're maxed their active values should be identical. As stated, theoretically you should be able to get the same tones with the pots in their stock positions, but many of us found it difficult to zero in on that sound with the pots set up that way. Mesa tone and gain controls are so sensitive and interactive that it can take a long time to get THE sound you're after. A common complaint.

I can't emphasize enough: I think the biggest benefit to the mod is increased USABILITY for those users who want the two channels to basically behave the same way. Many users (maybe most) don't really have that issue for whatever reason, so they should just leave theirs alone.

Keep in mind: merely being able to "clone" channel 1 isn't really the point in and of itself. The point is that what many of us wanted was a Drive channel that had the same character, at the core, as Ch 1. At least for me this meant maintaining this character within the range of control settings that I typically use. For instance: I don't use my amp with the Gain maxed. Sure, the channels sound the same then, but what's the point of that?

Post-mod Ch2 still has scads more fat, rich gain than Ch1, it's only when the Drive switch is disengaged that they are "identical". Switch it on, and you're in saturated gain heaven.

Regarding the nasally/wet blanket thing, that is one of the complaints that the modders seem to feel is fixed with the mod. It sounds like you might be happy modding your amp if that's something you don't like.

Hair-trigger volume: This may be a setting-specific problem, but I do not have this problem with my amp at all. Again, usability: if that were a problem for me, I'd reverse the mod in an instant. I use my amp in situations that require very civilized volume levels, and I feel like I have pretty handy control over my volume.

I also found Ch2 needed a bump in setting compared to Ch1 after I did the mod, even as they were "cloned" tonally. By now, however, my settings and tubes are all different and I find my Ch1 volume is about a click or two higher than my Ch2 most of the time.

That brings me back to the cloning thing: again, it isn't really the point, it's more a way of referring to the basic character of the channels being more aligned. Usability. And I found that once I'd swapped all the Mesa preamp tubes out of my amp for a cocktail of different tubes, I actually can't quite clone the channels anymore. Probably just having two different tubes in V1 and V2 will make the channels sound slightly different. However: my amp sounds AMAZING. So I couldn't care less. :)

Hope that helps! You should probably just do the mod, if you don't feel comfortable doing it yourself it should be an easy one for a tech.

hi djw!

thanks very much for your thoughtful detailed, prompt reply!
(btw i've gotten alot of good info from your posts in the last month or so!)

i'm gonna have my tech do the mod right after christmas. i'm looking forward to hearing the results. if anyone else thinks the ch2 volume becomes 'hair-trigger' please post.

have u tried the reeder mid-mod? do u hear a difference? improvement? thoughts?

thanks again!

Yes, I did the mid mod on Ch2. I did it on the clean channel too, but undid it soon after; ch1 really doesn't need anything, it's pretty perfect as-is IMHO. But ch2 does benefit from the mid mod. It's more subtle than the pot swap, but at higher volumes it seems to keep the low-end fartiness to a minimum.
