• Improve you tone with this simple passive addition. This is a special combination of capacitors, resistors along with an inductor to produce a really useful enhancement to any guitar or bass without requiring active electronics.
• Great substitution for the 2nd tone control on your Strat!
• As you turn the knob down from 5 to 0 this control pulls the midrange frequencies out while leaving the high and low frequencies intact. When set approximately between 2 and 3 I find this to really emphasize the signature "Mark Knopfleresque" bell like strat tones when using a clean tone. Some people report the tone to have an almost "acoustic" like quality. When you turn the control from 5 to 10 you get a slightly thicker sound wtih a bit more of a midrangy honk to it. The control is neutral in the 5 spot.
• Designed for use with guitars and basses equipped with single coil pickups. It will also work with humbuckers, however the effect of the control from 5 to 10 is not as dramatic since humbuckers are already thick sounding.
• Comes professionally wired on a brand new 500K custom taper split shaft pot with a center detent made exclusively for Rothstein Guitars by CTS corporation. The part number for the pot is RG500D (RG is for Rothstein Guitars) and the word "detent" is stamped across the sides. You won't find a pot like this anywhere else! Summary of custom features:
  CUSTOM TAPER: After much R&D we found the perfect taper for this mod which is a hybrid between audio and linear taper
  CENTER DETENT: Due to the overwhelming request by customers the pots has a detent at 5.
• A couple of other manufacturers sell these, but as far as I know we are the only one selling them with genuine Sprague Orange Drop capacitors which are among the most highly regarded capacitors in the industry.
• Includes detailed instructions.
• Very simple to install (soldering iron required).

• Great option for a guitar with a single tone control like a Tele.
• When the push-pull switch is down this functions as a standard tone control which cuts highs.
• When the switch is in the up position it becomes a mid-sucker that scoops mids as you turn the knob down. Like RG500D above when set approximately between 2 and 3 I find this to really emphasize the signature "Mark Knopfleresque" bell like strat tones when using a clean tone. Some people report the tone to have an almost "acoustic" like quality.
• Mounted on a 500K push-pull pot.
• Very simple to install (soldering iron required).
• Includes detailed instructions

• By popular demand we have voiced a passive mid shaper for the bass guitar. This is a great option for any passive bass.
• When the push-pull switch is down this functions as a standard tone control which cuts highs.
• When the switch is in the up position it becomes a mid-sucker that scoops mids as you turn the knob counterclockwise. On a bass this works great for slapping.
• Mounted on a 500K push-pull pot.
• Very simple to install (soldering iron required).

• SOUND CLIP: Here is a sound clip of this control used in a Jazz Bass recorded by pro bassist Tony Senatore. Tony played a Mexican Jazz bass equipped with Nordstrand NJ4 pickups along with a Rothstein JX5 prewired harness with the MTB mid-scoop/tone switch. The sound clip plays the same 2 bar slap phrase 3 times :
  1. The first time the slap phrase is played in full treble mode
  2. The second time the same phrase is played in full bass mode. In other words, the push-pull switch is in the "down" position and the tone knob is rolled almost all the way down (to about 1).
  3. The third time the phrase is played in mid-cut mode and you will notice how the slaps and pops really jump out. To arrive at this setting, the push-pull switch is in the "up" position and the tone knob is rolled almost all the way down (to about 1).
