RADIAL BIGSHOT PB1 CLASS-A POWER BOO - Part Number 000175
BigShot PB1 class-A power booster Fully variable class-A power booster for solos Buffer drives multiple pedals and long cables Drag™ control load correction for natural tone Ultra linear performance for natural boost Compact and easy to use – great for pedalboards The Radial BigShot PB1 is a combination power booster and buffer designed to provide exceptional sonic performance for pedalboard users in a compact and simple package. It provides 15dB of boost, accessed using a guitar pick via a rear-mounted recessed control that is protected from foot stomp damage. Unlike class-B preamps found in most pedals that color the tone and give buffers a bad name, the BigShot PB1 features 100% discreet class-A circuit topology for the utmost in sound quality. Class-A circuits are preferred due to reduced zero cross distortion, improved phase response and the resulting smooth Bessel curve of evenly cascading harmonics. This is augmented with Drag™ control, a variable load correction circuit that lets you dial in the perfect impedance to match the original tone and feel of your guitar and amp combination. With the PB1, noise is reduced while performance is augmented. Long cable runs are finally possible. And when you hit the boost, you get smooth clean control like you never though possible. The BigShot PB1 is likely the finest guitar power booster ever made. BigShot PB1 Development After the successful launch of the Tonebone Switchbone, scores of guitarists told us how much the liked the power booster. They liked the fact that it did not color their tone and the buffering helped quiet down their system. The natural progression was to incorporate a refined version of our booster in the Loopbone. The PB1 follows the same topology by providing a no-nonsense, 'best-of-the-best' combination power booster and buffer for the most demanding guitarists. But what makes a power booster better? How about buffering? Is this not a total affront to the concept of true-bypass switching? In many ways, the answer to the second question is subject to personal taste and akin to asking: what is better; a Strat or a Les Paul? Let’s start with the easy question… What makes a great power booster? It is safe to say that the very best devices ever invented have a base in science and technology. A fast sailboat, a winning race car, a great sounding amp, or a great feeling guitar all begin with someone taking the time to work through the problems and find a winning balance. Most guitar products that made their debut since the first Fender Using the BigShot PB1 Following the block diagram on the left, you can see that the PB1 is extremely simple to use – you plug your guitar into the input jack and your amp from the output jack using standard ¼” guitar cables. For safety, always make connections with your amp volume turned off. Connect a standard Boss style 9V power supply to the PB1 for powering. There is no on-off switch – leaving it on will not harm it Before you play, set the 'DRAG' (pickup load adjustment) and 'GAIN' (boost level) controls to 12 o’clock using a guitar pick or screwdriver. This will give you a good starting point. Now, turn your guitar amp volume up a bit. Always test at a low volume to prevent system damage. If all seems ok, hit the BOOST footswitch. Adjust the 'GAIN' control to suit. Now go back and listen to the PB1 and how the Drag control works. Full clockwise takes the Drag control out of the circuit and will result in a brighter tone. Full counterclockwise will darken the tone. If you use an active guitar, the Drag will have very little effect. Find the ‘sweet spot’ that works for you and start playing. Remember, you will have to stop and get some food at some point! Best you should arrange to have someone come find you or else you may starve!
