I'll be honest - there's not that much variation between different tremolo pedals. But seeing as you're only getting to have one on your pedalboard, and therefore the one you purchase now's likely to last you for years, you would possibly also take the time to form the proper decision.

There's a huge amount of pedals on the market. The differences between them are often subtle. the primary and most blatant factor is that the sound because if that's no good, no fancy bells and whistles are getting to make your pedal worth having. therefore the initiative is to possess a listen! Your local guitar shop won't have an outsized selection of tremolo pedals, but any pedal you'll consider goes to possess an indication video of it somewhere on the web, if not from the manufacturer then from dozens of review sites. YouTube may be a good place to start out.

(As an aside, before you opt whether you would like to feature a tremolo effect to your arsenal, I suggest you create sure you recognize exactly what 'tremolo' is! Educate yourself on the difference between 'tremolo' and 'vibrato', because many guitarists get the term confused.)

Other than the sound, another thing to require into consideration is that the various modes and settings that different pedals have. most pedals will have the quality three adjustable parameters: speed, depth, and shape, although some may name them differently, e.g. by labeling 'shape' as 'wave', or 'speed' as 'rate'. If a pedal doesn't have those three settings, it had better sound really good! Either that or you will have to be proud of the sounds it can produce because it won't be as flexible as pedals with all three.

The 'speed' and 'depth' settings are simple enough. the previous controls the tempo of the effect, dictating what percentage times per minute your volume will rise and fall. The latter controls just what proportion the quantity will vary by. Turn it down and you will barely hear a difference. Turn it up and your smooth sound will become a jarring shudder.

The 'shape' setting is the one where you will see the foremost variation between pedals. In its most elementary form, this just varies the waveform of the tremolo sound, often between a 'square wave' type sound and a 'saw wave' type sound. It's hard to explain what these terms mean in terms of the particular sound they produce. If you're unfamiliar, search YouTube for 'square wave' and 'sine wave' and have a hear both. As a rough way of putting it, a wave produces a 'smoother' sound while a square wave produces a harsher one.

Some other features you would possibly see are:

A tap-tempo button. this is not quite common but are often incredibly useful. It allows you to line the speed (or rate) of the tremolo effect with much greater precision, in much less time, which is clearly very handy in live situations. this is often especially useful if you would like to vary the speed to match a song that's already being played - you'll just beat out two beats and be done, instead of having to regulate a knob, play, hear if it sounds right, adjust again, play, rinse, repeat.

You might even be concerned with the sort of bypass that the pedal uses. If you've got tons of pedals in your chain, the signal could be faded or muddied a touch along its thanks to your amp, leading to a loss of quality or volume. The way during which the signal passes through each pedal when that pedal off has an impact on this. The gold standard to seem for maybe a pedal with true bypass - this suggests that when the pedal is off, the electricity will pass straight from 'input' to 'output' as if the pedal was just another few inches of cable, minimizing any damage to your tone. Pedals with true bypass are generally costlier. If it is vital to you, go for it, but to be honest, I've found that unless you are a real audiophile it doesn't make an enormous difference.

So in any case, are there are any tremolo pedals I recommend? Well, two come to mind. If you are looking for an easy, no-frills pedal that'll get the work done and zip else, I'd recommend the Boss TR-2 Tremolo. It's affordable, and sort of ll Boss pedals it's built like a tank and can last you forever.

If you would like extra flexibility, however, and have a touch of additional money to spend, my recommendation would be the Cusack Tap-a-Whirl. This pedal has an utterly insane amount of features and settings (including a faucet tempo button!) and you'll customize it to your heart's extent. I'd be surprised if there is a single tremolo-like sound in your head that you simply won't be ready to produce with this pedal.
