Thanks, we will contact you soon

I want my custom Cornell amplifier to be based on an existing amp

You've told me who makes that amp - now I need to know which model you are talking about

Is this a particular vintage? Or maybe it's an amp that is still being made.


Some of my customers have a beloved amp that's on its last legs. I can rebuild them! Some of my customers want a new and reliable version of a classic amp that they don't own.

What is it about your custom amp that will be different to the original on which it's based?

Go into detail! It could be that you want to add features that the original lacks or maybe you don't use some features. For example, some people don't want an unnecessary reverb circuit. Some people want to add a well-known mod to a classic design of amp.

Any final thoughts or comments

Don't worry, there will be plenty of time to double-check and refine your custom amp before I begin construction but this is a good opportunity to mention any special features or attributes. It helps for me to know how you plan to use your amp and your playing style.

The chassis is the stainless steel frame that contains your amplifier circuitry. We have a wide range of existing chassis layouts but some customers want a totally unique setup that we produce using CNC design. When we build you a custom amplifier this is one of the decisions we help you to make.

Loudspeakers

The great thing about a custom amp is you get exactly the speakers you want. These are some of my favourites but we can source any type you prefer.

Cabinet

I can build anything between a tiny combo and a huge backline stack

Your cabinet will be built specifically for your amp. We have a great range of cabinet designs but you might need a new design that has do be drawn up, designed and built.


This is purely a matter of visual taste!

I have a great stock of amp covering materials but if you want something unusual please tell me.

Tolex comes in a range of textures, all of which are hardwearing

I have a large stock of grill materials to match the speaker covering.

We're starting to get into fine details now. Most people want the handles and corners to match. Some people need fittings that will survive life on the road. Some people want a gorgeous brown leather handle embossed with the Cornell logo. We will cover these fine details when finalising your order.

What type of power valves?

The type of power valves decides how loud your amp will go, the character of sound and type of distortion

You can get clean headroom at louder volumes if you have more valves

Are you looking for an American or British sound from your amp?


With your style of guitar playing will you routinely push your amp into distortion?

Generally speaking the USA has 110 Volt mains and Europe is 240 Volt mains.

You can have a flexible setup that allows you to plug in different loudspeaker cabinets or we can make it simple. There are various ways of making the setup flexible. You might want a touring grade amp setup that will survive life on the road and complexity might not be the best thing.

Signal chain features

Do you want a simple or complicated amp?


This lets you drive your amp to distortion at lower volume levels. A Master Volume amplifier will have this type of volume control arrangement.


We use the best Accutronics spring reverb trays

Some guitarists like a single tone control, others prefer to have bass, middle and treble controls

Single channel amps are more purposeful, twin channel amps give you more versatility


Many amps have a presence control - it gives you more treble


This four-way switch cuts the power of your amp down from 100% to 15%, 2.5% and 0.5% which lets you produce the right tone on stage and at home.


An effects loop is an input and output that lets a user insert effects between the preamp and eq section and the power section of an amplifier.
