What Jim Dunlop say....
MXR M133 Micro Amp
This device adds a preset amount of gain, using a single control. With a guitar, this lets you boost your signal for lead work, adjust between two different guitars with unmatched output (i.e. humbucker to single coils), or it can supply a permanent boost in a long effects chain where signal dropoff is a problem
A wide range of artists stand by the MXR Micro Amp including: Motorhead, Mick Taylor, Alt-J, Foals and Black Stone Cherry.
How to use the MXR M133 Micro-Amp:
To set up the M-133, plug your instrument into the Input jack and your amplifier into the Output
jack. Turn on the effect with the footswitch toggle, making sure the red LED is ON to indicate that
the effect is active.
Next, adjust the Gain knob while toggling the footswitch on and off, comparing the volume of the
unmodified (light off) signal with the modified (light on) signal. Match the gain level as closely
as you can to the unmodified signal. This is your reference point: if you plan to make adjustments
during your performance, it might be useful to mark this position with a piece of masking tape and
a marking pen. (Write on the tape, not the stomp box!)
Then adjust the Gain knob to the desired amount of added gain or cut that the situation calls for.
(If you’ll need to find this position again during performance, make another mark on your tape.)
A common use of the M-133 is to leave it turned off until it’s time to solo, then kick it in for a
quick level boost during the solo. You can easily apply it to ANY situation where two different,
quickly accessible playing volumes are appropriate.
Our chosen couriers are currently operating as normal and all orders should be delivered on time. DPD are also now operating a "contact-free" service as a standard process and customers will not be asked to sign handheld units.
Order before 2pm, Monday to Friday, for same-day dispatch of in-stock orders. Very heavy items such as pianos may take longer to deliver. In-stock orders placed over the weekend will be dispatched on Monday. Estimated delivery times for out of stock items are to be used as a guide only, these items may take longer than estimated to arrive. While we try our best to ensure rapid delivery of your order, delays may occur which are outside our control, and delivery of large or bulky items, or to remote or non-mainland addresses may take longer than estimated.
Most UK deliveries are shipped by our trusted courier, DPD. You'll receive an email with a delivery day, tracking and a one hour estimated delivery window on the morning of delivery. While we can't specify the time of the delivery, if it's not convenient, you can arrange directly with DPD for an alternative delivery date or request the parcel be left with a neighbour.
For heavier items, we usually ship UK deliveries by TNT. You will receive an email with tracking details when we ship your order.
Delivery to mainland UK addresses is free on all orders over £99. Delivery charges are based on the size and weight of your order and, in some cases, your location.

We use a few different delivery couriers, depending on the items being sent, your location, and the delivery service you've chosen:
Most orders will need to be signed for and we advise you make sure to check your parcel/s for any damage before signing. If no-one is available at your address, a card will be left so you can arrange a re-delivery directly with the courier. Redirection of an order after it's been dispatched may incur an extra charge from the courier.
Delivery charges displayed apply to most UK mainland addresses. Deliveries to Northern Ireland, UK non-mainland, and European addresses will cost more, and carriage charges will be shown at the checkout before you place your order. Free delivery offers may not apply to some remote/Scottish Highlands addresses.
