Hello, has anyone researched or had a "Cut Control" installed on an RX ES ? I have a 2x12 combo with 2 - Golds ! (I know, HEAVY and LOUD !) and it's been a tough amp to use because of the volume issue, I am getting the Master Volume mod because of this, and from what I gather from the message board, I will love it ! However, I am also considering having my tech install a post eq cut control, much like my MAZ 38, which works unbelievably well ! The reason I feel I would like, or need it on the RX ES, is that I find I need to back the treble down (definitely with my Tele's) to avoid "Ice Pick Highs" to the point that it effects the gain structure of the amp in a negative way. On my MAZ 38 this is completely avoided because of the ability to dial out that edge with the cut, while still being able to run your treble at a decent level to preserve a nice robust gain curve. Am I the only goof ball that ever thought of this ? Any feedback will be appreciated !!!
FYI, Shot an e-mail to Don at Z, and he informed that he thought the Cut Control should not be a problem to install in my RX-ES (along with the MV mod) I am planning on sending her in and will report the results back when done.

Wow, that is an interesting experiment. I know what you're saying about the gain structure and the treble control. Keep us posted!
Here's a tip for you: have you tried different EF86's? Tubes like the Dario Miniwatt are pretty bright and chimey to me, which are great for amps like the 'Ray. However, I've got a couple of Mullard EF86's that I think are a lot more mellow than the Dario. I didn't like it in V1 of my other Z's but it sounded great in my RxJr with Teles and Strats. Give it a try if you can.
Phil, Thanks for the suggestion on the EF86. I actually already have a Mullard that I got from KCA Tubes, which is probabley the quietist EF86 I've ever heard and yes a bit smoother than others. Also, I just got my RX ES back with the mods installed ! I ended up having them installed locally by an amp tech that I have worked with for years (Dan Russel of Blitz Amplification), Dan was the original circuit designer of the Naylor Super Drive amps and has extensive experience working on Z's, Matchless, Vox, and the like, so a very compitant tech for sure. I wanted to mention this because it was critical for me to ensure that the cut and master mods were installed as they would have been by Dr. Z. My reason for not having Z do the mods was simply to avoid the dreaded shiping of a 2x12 Rx Es beast and risking damage, ect..... Both mods were installed on the rear panel of the chasis, and knobs, pots, and even exact wire were used to ensure that factory apeerance and quality were in tact. I must report that my initial review of the mods is very positive. The master volume goes without saying, and there are several threads on this site verifying that for sure, completely transparent and dosen't squash the open feel of the RX Es at all, just allows you to bring her back to a reasonable level while pushing the pre amp section into OD. The cut mod is exact to what I wanted, it functions (at least as I hear it) exactly like it does on my MAZ-38, just allows me to dial back that edge while keeping the trebble control around noon to keep the gain structure nice and snappy ! For referance, I run two 12" Celestion Golds in my combo, and I may consider swapping one out for a GH-12 to get a little more flexibility. I would certainly recomend these mods to anyone that has had a similar experience with their RX Es, if you can send your amp in to Z, thats the the best move, unless you have a compitant tech you trust locally as I did. I will follow up after I sit with it a bit longer and gig out, ect....
Back on this cut and MV. Any more input? I keep my treble down lower to avoid the highs on teles but never messed with it enough to know how it effects the gain structure. I might try messing with that tonight and report back.

GuitarZ: Reminds me of buying my Honda. When they tried to sell me the maintenance package, I said "Is your car not reliable?" Long story short my wife teamed up with the sales lady to buy the maint package. Never again!
