Ever wondered how you could get that iconic sound and character of the delta blues? It's all here at the tap of your toe inside the Wampler Clarksdale Delta Overdrive Pedal! Derived from the well-known Tube Screamer circuit, this incredible pedal offers a handful of unique features that only Wampler could bring you. Specifically developed to bring you all of the tone and response of the original Tube Screamer, yet still offer a newer, more flexible range of sounds for you, the player, to explore.


Offering exceptionally transparent drive tone when played at lower volumes, the Wampler Clarksdale Delta Overdrive Pedal delivers an attacking and cutting, vintage overdrive that will satisfy even the most particular of ears. You really don't have to sell your soul at the crossroads, just plug in a play through this little beauty for all you could wish for!


What Wampler say about the Clarksdale Delta Overdrive Pedal:


At the crossroads of Highway 61 and Junction 49 lies the official crossroads of Clarksdale, Mississippi – the birthplace of the Delta Blues. This historic town, and the famous music that was created there, is responsible for the inspiration behind this pedal – The Clarksdale Delta Overdrive. The Clarksdale is Brian’s take on the world famous Tube Screamer® circuit – with a few great Wampler styled improvements of course. Brian wanted to create a pedal that would be true to the sound and feel of the original but would have a wider range of tonal options – to satisfy even the biggest tone chasers out there.


Unlike the traditional screamer type of overdrives, The Clarksdale has a more transparent drive when turned down and even more usable gain that won’t fizz out when cranked up! Now you can dial in your tone faster and more efficiently no matter what the gig is! The Clarksdale will be the last pedal that is based off this familiar vintage circuitry that you will ever need. Your search for the perfect vintage midrange infused overdrive is finally over.


Input and Output: 

The input jack is located on the top right of the pedal, above the treble control and the

output is the other side of the power input, above the bass control.


True By-pass Relay Switch:

We use a true-bypass relay because it utilizes a quieter and smoother switch that is more reliable than traditional bypass switches. Your original tone/signal will remain unaffected when the pedal is not engaged.



This control adjusts the output level of the Clarksdale. The Clarksdale was designed to have higher output. This allows the Clarksdale to have more headroom when needed. The output volume, Gain and Tone controls all have an impact on the total volume, so you might want to adjust the Volume after you have dialled in the other controls. Re-adjustment might be necessary if you get it to the desired level and still need to tweak the sound.



This control adjusts the total amount of gain that is applied to the signal path. Turning the Gain control clockwise will increase the amount of gain in the circuit.

Whether you use a little gain for a smooth break up - or crank your gain all the way up for great thick, vintage style over-driven tone - your drive will stay true and not fizzle out as much as the original Screamer style of pedals.


Smooth/ Lift Switch: 

The Clarksdale features a small toggle switch that is labelled LIFT and SMOOTH. The Lift/Smooth switch will allow a player to either sit in the mix with the Smooth setting or allow your leads to stand out with the Lift option.



Adjusts the amount of bass applied to the effected signal. If you are using a Stratocaster® style, single coil guitar rather than a humbucker loaded instrument, you may find you need more bass to “fatten” up the tone. When in the fully counter-clockwise position, the tone will be much thinner and brighter and when fully clockwise it will

be fuller, darker and heavier around the low end.



Adjusts the total amount of midrange that is applied to the effected signal. Unlike a traditional Screamer style circuit that had an ever present midrange bump – you can

now choose to dial in less or even more mid-range as you

see fit.



Works in the same way as the bass knob but controls the amount of treble on the effected signal. Again, fully counter-clockwise the treble is reduced considerably and clockwise brings it forward. You may have to tweak both the treble and bass controls simultaneously to find your sweet spot.


Power Requirements:

The pedal can be powered by a 9V battery. The battery terminal is located inside the pedal. If using a power supply, power needed for the pedal is 9V DC, regulated, centre pin negative, as supplied by most standard Boss™/Ibanez™/Etc. supplies. The pedal can be safely powered with a multi-supply, like the Visual Sound 1SPOT™. The pedal was designed explicitly around the usage of a 9V DC power source, and is intended to sound its best at 9V. To avoid damage to the pedal, do not exceed 9V DC, do not use centre pin positive adapters, and do not use AC power. Using an incorrect power adapter can lead to damage and will void the warranty on the pedal. This pedal draws 17mA.


Please note: If you are using a battery, it will drain when the input cord is plugged in.

CITES regulations concerning the export of items containing certain woods affect any guitar sold ouside of the European Union and which contains any quantity of either Rosewood or Bubinga.  In these cases, an additional charge of £80.00 will be levied per species after the sale to pay for the required re-export certificate.  There will be a delay in dispatching any guitar containing either Bubinga or Rosewood of up to 4 weeks while we obtain the necessary certification for export. As the charge is per species, where a guitar contains both Bubinga AND Rosewood, the charge is doubled to £160.00.  We will contact you following your purchase of any guitar containing a controlled wood and advise of the charge once you have placed the order.  You can make payment for the charge by sending a Paypal payment to us at: sales@fxpedal.co.uk. 

Note that CITES only applies to guitars containing Rosewood or Bubinga that are being exported outside the European Union.  Guitars being delivered with the United Kingdom or in the European Union will be dispatched as normal.
