The Mark Sampson designed Hightop is everything “Mark Sampson” in a box. Mark is known for his recreations of the classic AC30/Top Boost tones when he worked for the “other” companies. This pedal is about the best you can get if those “chimey” Beatles type tones float your boat. Play the Hightop for 10 minutes and then turn it off and you will wonder who put the blanket over your amp! This is an actual “Top Boost” circuit reduced to transistors so, flat for the EQ is with both bass and treble all the way left. The cut control contours your highs and the interactive combination of all 3 EQ controls allows you to dial in your mids. Ceramic/Alnico gives you the best option for your choice of a speaker type. Alnico speakers have a certain breakup characteristic so if you want to emulate that, select Alnico. The same goes for the Ceramic speaker setting. Bring in the EF86 and dial it to your liking as well.
- Volume: The volume control can be very subtle depending on if you have the ceramic/alnico foot switch engaged. In alnico mode it is louder.
- Bass: The bass control is at unity all the way to the left just like a real top boost. You can add bass but it is very powerful. Adding only a touch is recommended otherwise the tone can become bloated.
- Treble: The treble control is at unity all the way to the left just like a real top boost. You can add treble but it is very powerful just like the bass. Adding only a touch is recommended here as well.
- Cut Control: The cut control allows you to set the interaction between the bass and treble while still having control over the highs without disrupting the setting you like between bass and treble. This interaction allows you to define your mids depending on where they are set. The cut control can dial in the intensity of the “chime”.
- EF86 Knob: The EF86 knob allows you to set the intensity of the EF86 sound once it is engaged with the EF86 switch. It is subtle but you will hear an increase in volume and harmonic complexity
- EF86 Switch: The EF86 switch simply turns on the EF86 sound, which is then controlled by the
- EF86 knob. The EF86 sound creates a very complex and gritty tone so try it with and without the alnico setting.
- Dimensons: 4.75″ x 3″
- 9 volt Negative tip adaptor and a 5.5mm x 2.1mm jack.
- 9 volt Battery

Ceramic/Aln: This is a unique function that allows you to recreate either the ceramic speaker sound
or the alnico speaker sound. The ceramic speaker sound is typically tighter and more
defined whereas the alnico sound is typically looser, brighter and more swampy
sounding. It all depends on the amp you are using but expect the alnico setting to be
All J. Rockett Audio Designs pedals operate off of the standard BOSS type 9 volt adapter or a single 9 volt battery. The power input is a 5.5 mm x 2.1 mm jack with the positive voltage on the outer sleeve. Using an external power supply will automatically disconnect the battery. Disconnect the input jack to preserve battery life when not in use or when not used with an appropriate, external power supply.
