BEHRINGER DIGITAL DELAY DD400 Digital Stereo Delay/Echo Effects Pedal Ultimate digital Delay/Echo effects pedal with 7 different modes - comparable to state-of-the-art studio processors This BEHRINGER product has been designed to compete head to head with leading products on the market 24-bit high-resolution stereo delay/echo with delay time up to 1.3 s and tap tempo feature Dedicated Mode, Time, Feedback and Level controls for awesome sound shaping Blue status LED for effect on/off and battery check Runs on 9 V battery or the BEHRINGER PSU-SB DC power supply (not included) First-class electronic On/Off switch for highest signal integrity in bypass mode High-quality components and exceptionally rugged construction ensure long life Conceived and designed by BEHRINGER Germany The BEHRINGER DD400 has an obsession with the past - the last 1.3 seconds of it, to be exact. What is delay? Delay is a synthetic echo that, in adjustable increments, repeats the notes you play on guitar. Each repeated tone becomes quieter than the previous one, until the repeats are no longer heard. This results in a thick, robust sound that can take on everything from the quick "slap" echo of classic rockabilly to the long, dreamy echoes found in psychedelic rock. Superior Sound This box will sing the fading, ghostly praises of every note you squeeze from your axe. With seven modes of delay to choose from, there is a vast pallete of echoes to explore with the DD400. Take advantage of its full 1.3-second memory or scale it back for a more abrupt echo. Just twist the dedicated Mode, Time, Feedback and Level controls to create the delay of your dreams. There is also a HOLD mode that allows you to loop a brief riff, then play over it. The blue LED tells you when it's on, and the first-class on/off switch maintains incredible signal integrity in bypass mode. You can power the DD400 with a 9 V battery or a DC power adapter.

Double the drive with the Vox Duel Overdrive pedal. With two overdrive circuits based on Vox's Big Ben Overdrive pedal, the Duel Overdrive provides footswitchable access to two sounds from a trunk full of classic and modern tones. With separate gain, volume and tone controls, you can set the pedal up with two totally independent overdrive sounds to compliment a clean-bypassed tone. To make it even more flexible, Vox added an assignable low-end bass boost function for fat-bottomed overdrive tones. Add the Duel Overdrive to your existing pedal setup and benefit from an unmistakably "real" valve overdrive. A tube in a pedal? Pretty cool. The COOLTRON series of effect pedals use a 12AU7 preamp-type tube at low voltage to deliver the kind of tone that, until now, would have been impossible to achieve in a battery-powered pedal. Want to know how it all works? Normally, tubes are used at high voltages and this restricts their use in battery-powered devices such as guitar effects pedals. Historically, attempts have been made to use tubes at low voltages in what has been dubbed "starvation" mode, but these circuits don't allow the tube to function in an acceptable manner. The tube simply cannot be biased to a satisfactory operating condition. Plus, the necessary heater (filament) current is too high to deliver acceptable battery life. Imagine how annoying it would be to have to change batteries every ten minutes during a gig! Here's what makes the COOLTRON system tick. The COOLTRON circuit basically operates by using two very special signal paths. The first is the "servo circuit," which provides the right conditions between the plate of the tube and the grid. This achieves controllable, stable parameters for the tube and provides the correct operating conditions for the tube to function as it would if run at a higher voltage. The second circuit is a patented power supply that provides a low voltage, low current supply to the heater elements in the tube. Since the tube is now running at such a reduced supply level, the anode current is much smaller than normal. This means that the amount of heat required at the cathode to achieve sufficient cathode current emission is much smaller ” hence the ability to run the heaters at a lower level and for COOLTRON pedals to run for 16 hours on 4 x AA batteries! The COOLTRON system provides true tube sonic performance at very low voltage and at reduced heater current ” ideal for inclusion into guitar effects pedals. COOLTRON guitar effects pedals offer valuable tube type sonic performance. SPECIFICATIONS Input: 1 guitar input Output: 1 line output Controls: gain, tone, volume, bass boost Tube: 12AX7 Power: 4 x AA batteries allows 16 hours of operation Dimensions: 6.63" W x 6.12" H x 2.52" D Options: 9V AC adapter USUARIOS DE MENOS DE 200 POSITIVAS O USUARIOS NUEVOS, SOLO SE ENTREGARA Y PROBARA EN PERSONA PREVIO DEPOSITO O TRASFERENCIA BANCARIA ENVIO Y ENTREGA: POR MRW UNA VEZ CONFIRMADO EL DEPOSITO, EL PRODUCTO SERA ENVIADO EN LA MAYORIA DE LOS CASOS EN 2 DIAS HABILES A MAS TARDAR.EN CASO DE ENVIO EL PRODCUTO SOLO SERA ENVIADO A LA OFICINA DE MRW MAS CERCANA AL DOMICILIO O TRABAJO DEL COMPRADOR PARA QUE LA PASE BUSCANDO Mis Artículos a la venta

Weep, wail, and moan with blues-drenched tone. The DigiTech Screamin' Blues Overdrive Distortion Pedal is designed for guitarists who need a pedal that gives them total control of their tone and is highly responsive to playing dynamics. Playing the Screamin' Blues pedal lightly produces mild overdrive, but dialing up the gain and digging in hard makes it sing with ultrarich harmonics and sustain. Low and High tone controls give you the flexibility to boost or cut the bass and treble frequencies. The Level knob boosts the output level of your signal, and the Gain knob dials up the distortion. An Amp output on the DigiTech Screamin' Blues pedal goes to your amplifier and the dedicated Mixer output has a cabinet emulation circuit that lets you run direct into a mixer or recorder when you don't want to lug your amp along. FEATURES Level controls distortion output level Low adjusts boost and cut of bass frequencies High adjusts boost and cut of upper harmonics Gain sets the maximum distortion amount when playing your hardest Dual outputs: The Amp output is for connecting directly to a guitar amplifier; the Mixer output features Cabinet Emulation circuitry for connecting directly to a mixing board or recording device Got the blues? If you don't have this pedal, you do. Get it now and learn to really cry.
