The First Comprehensive Rosin System for Double Bass
Each pack contains 2 rosin recipes of your choice

The Amber Range is the first comprehensive rosin system for Double Bass, and the newest rosin range from Leatherwood Bespoke Rosin.

The Amber Range is designed to help Double Bass players find the exact combination of stickiness, grip, traction & lyrical quality to suit their playing needs.

The Amber Range’s rosin recipe chart offers an almost unlimited choice of recipe grades, ranging from hard rosins (similar to cello rosins) through to recipes that are very soft and sticky, with a helpful guide on how to choose the right recipe for your playing. By varying the recipe grade, Bass players can have more control over sound and response characteristics such as Grip, Traction, Lyrical Quality, and Powder Content.

The Amber Range offers 2 rosin recipes per pack, and Bass players may choose any recipe along the the chart. This can be 2 cups of the same, or different recipes.

Different grades of rosin recipe can be mixed on the bow for further enhancement. For example, a player might first apply the 35% grade as the ‘base recipe’, then occasionally add the 50% for extra grip.

The Amber Range only uses ingredients with low or no evaporative volatility, which means in normal playing circumstances* the rosin will not degrade over time. Normal playing circumstances means there is no exposure to extreme heat, cold or humidity. A ‘normal’ temperature range is considered 5°C - 25°C

The Amber Range has evolved over a 6 year period of trials and consultation with Bass players from all over the world, including players from Orchestras including the Berlin Philharmonic, London Philharmonic, New York Philharmonic and many others. We have worked with bass Orchestral bass players (professional, amateur, student, college), pedagogues, Jazz and improvisatory / experimental players, solo and chamber music players, and players of bowed electric bass. Our bass rosin recipes have journeyed through a whole spectrum of recipe formulations and ingredient varieties in order to meet the demands these players and their varying playing contexts. In order to comprehensively meet these demands, we now present the Amber Range, which brings together all of this research and consultation, offering Bass players a range of recipe choices, from very hard to very soft rosins, that can cater to differing playing needs, sound needs, grip strength and climactic conditions.

How to use The Amber Range

Use the recipe grade chart (above) to choose your desired recipes (2 per pack). They can be the same recipe or different recipes. When you receive your rosin:

  • Carefully separate the walls of the rubber cup from the rosin

  • Lift the rosin slightly out of the cup or peel down sides of cup

  • Keep your fingers touching the sides of the cup, not the rosin

  • Apply with fast and strong bow strokes, with heavy pressure on the rosin.

  • Swipe towards the centre of the rosin to avoid chipping

  • When you apply the rosin for the first time, apply quite a lot, about 6 - 8 swipes. This helps the rosin warm up and melt on to the bow.

  • For ongoing use, apply 2 - 4 swipes as required.

  • When first opening the pack the surface may appear with white powder. This is just a result of the rubber lid touching the rosin during shipping and will not affect usage.

  • To melt your rosin back into shape, just sit it in the cup on a flat surface in a warm environment and it will gradually melt back into the shape of the cup. Then allow it to cool and harden before using again

Here are some commonly asked questions:

How do the amber range recipes compare to other rosin brands in grip and stickiness?
A recent trial group of professional bass players made the following general comparisons:
- 35% was similar to Nymans
- 45% was similar to Pops
- 50% was similar to Oak
Please keep in mind that these comparisons have not been decided through any formal trial or research, and are just the collective opinion of a small group of bass players on one particular day. This group were indoors with an ambient temperature of about 23°C. All our recipes will feel different depending on the climate (temperature) they are tried in.

Which recipe is best for my climate?
The higher the percentage the softer the rosin. Firstly work type of playing context you want the recipe for, then pick a higher grade if you are in a colder or dryer climate, or a lower grade if you are in a hotter or more humid climate. For example. In Singapore or Mexico, the 55% - 60% might be too soft in those hot climates, and these rosins may be more like a liquid, so a 40-45% recipe would be more ideal here. However in Scandinavia (very cold and dry climates) the 55% - 60% will be harder and not as soft, therefore ideal.

Will the rosin melt in my case?
The rubber cup and lid will securely protect and hold your rosin quite tightly, and with normal travel and usage it won’t melt out. The Linen bag will also protect both the case and the cups from any further risks.

Can I melt it back in to shape?
Yes, just sit the cup in a warm place (over 23°C) and it will gradually melt back into shape. Lower grades take longer to form back into shape.

What ingredients are used in the rosin? are they safe for my bow?
The rosin ingredients we are use are derived from pure pine resin. They are safe for the bow. The higher the grade, the less powder rosin included.

How can I clean my bow hair after using the rosin?
Use a fine toothed comb or clean toothbrush to comb rosin out of the hair. If it is powdery, use a dry cotton cloth (similar to what you would use to clean the strings) to wipe excess rosin off the bow

Can I mix recipes on the bow?
Yes. You might find your ideal recipe is a mix of a harder and softer grade. This is why we provide 2 recipes per pack.
